Mesothelioma treatment options depend on many internal factors such as: stage, location, and the patient’s age and desires. Important external factors to consider include the experience level of the oncologist with mesothelioma cases and whether or not a rural dweller would have to be transferred to a larger city for aggressive treatment or palliative care.

Patient survival rate is determined to be up to a year; while some leading cancer centers have reported life expectancy after diagnosis to be as much as five more years.

Screening

Imaging tests allow doctors to see a picture of the cancer site. These tests could include x-rays, CT scans (computed tomography), or MRI (magnetic resonance imaging).

New Screening Instrument: The Mesomark Test

The Food and Drug administration has just approved (January 2007) the world’s first in-vitro test for mesothelioma. The Mesomark assay test, developed by Fujirebio Diagnostics is administered to patients diagnosed with biphasic or epithelioid mesothelioma by a simple blood test. The test measures proteins within the blood that reflect changes in the patient’s tumor volume, a key factor for monitoring patient status and response to therapies.

Traditional Treatment Types

Surgery, removal of the entire lung and a part of the chest lining, the diaphragm and part of the sac surrounding the heart.

Thoracoscopy is the insertion of an endoscope which is a small narrow tube, containing a tiny cameria into the pleural cavity to look directly at the tumor. Pathologist’s perform a biopsy to collect a tissue. Often, chemical pleurodesis (draining fluid in the intrapleural space), can be accomplished during the same procedure.

Mediastinoscopy, another type of surgical incision is sometimes used to stage the extent of disease when enlarged nodes are seen using imaging techniques.

Laproscopy is used in mesothelioma patients when imaging techniques suggest that the tumor has penetrated through the diaphragm. This information is important in evaluating a patient for potential pleurectomy or extrapleural pneumonectomy.

Radiation Therapy (using high-dose x-rays or other high-energy rays to kill cancer cells.

Radiation – Although mesothelioma tumors are highly resistant to radiotherapy, these treatments are sometimes used to relieve symptoms arising from tumor growth, such as obstruction of a major blood vessel.

Radiotherapy is commonly applied to the sites of chest drain insertion, in order to prevent the growth of the tumor along the track in the chest wall.

Chemotherapy – is used to stop the cancer cells from growing and dividing.

Immunotherapy: Heated Intraoperative Intraperitoneal Chemotherapy requires the removal as much of the tumor as possible followed by the direct administration of a heated between (40 and 48°C) chemotherapy agent, into the abdomen for 60 to 120 minutes and then drained.

Palliative Procedures

Pleuroperitoneal Shunt is a procedure where a catheter is placed under the skin from the pleural to the peritoneal cavity. This procedure raising concerns as the catheter can cause damage by embedding itself into the abdomen.

Pleurectomy, a palliative procedure, may be performed when more extensive surgery is not an option. The procedure does not effectively remove all tumors. It is considered the most effective means of controlling pleural effusion (fluid buildup) in cases where the lung’s expansion is restricted by the mesothelioma.

Potentially Curative Procedures

These procedures are performed with “curative intent”.

Pleurectomy/Decortication is usually performed on patients with early stage pleural mesothelioma disease (Stage I and selected Stage II), and attempts to remove all gross tumor.

Extrapleural Pneumonectomy is surgery to remove a diseased lung, part of the pericardium, part of the diaphragm and part of the parietal pleura. This type of surgery is used most often to treat malignant mesothelioma and is combined with traditional chemotherapy and/or radiation, gene therapy, immunotherapy or photodynamic therapy.

Cytoreductive Surgery removes visible tumors in the peritoneal cavity. The remaining cancer cells are treated by Intra-Peritoneal Hyperthermic (heated) Chemotherapy (IPHC) and then delivered to the abdominal cavity.

New or Experimental Therapies

Gene Therapy: The best known tumor suppressor gene is called p53. If this gene is damaged or non existent oncogenes or cancer genes multiply at an abnormal rate. The main focus of gene therapy for mesothelioma involves injecting a virus that has been modified in the laboratory. The virus is injected into the pleural space in the chest, where mesothelioma develops as an attempt to kill the cancer cells.

Drug or Vaccine Therapy

Patients with mesothelioma have much higher levels of vascular endothelial growth factor (VEGF) a chemical controlling blood vessel than people with any other type of cancer. Trials are being conducted to see if VEGF can be blocked, thus stopping the growth of blood vessels feeding the mesothelioma tumors.

Bevacizumab is a drug vaccine currently in use. One trial recently reported that this drug may increase survival for patients with lung cancer. An American phase 2 trial tested bevacizumab for mesothelioma, in combination with chemotherapy drugs. Bevacizumab is still in the experimental phase and much larger trials are needed before we will know how effective it will be in treating mesothelioma and other types of cancers.

Photodynamic Therapy (PDT)

In Photodynamic therapy a drug called a photosensitizing agent is injected into the bloodstream and absorbed by the body’s cells rendering the cells sensitive to light. When the area to be treated is exposed to laser light, the cells are killed. PDT has to be combined with surgery to treat patients in the early stages of mesothelioma. PDT is still in the trial stages and very experimental.

Clinical Trials and Eligibility

Clinical Trials provide research by using a sampling of people affected by the cancer. The National Cancer Institute states that the purpose of most listed clinical trials is to test new cancer treatments or new methods of diagnosing, screening for or preventing cancer.

Eligibility requirements for clinical trials are not the same; each study has specific guidelines for participation. Some trials allow participation after other treatments have failed, while others require that the patient did not have prior treatment. Choosing a clinical test should only be done after a medical consultation.

Prevention trials - study ways to reduce the risk, or chance, of developing cancer. Most prevention trials are conducted with healthy people who have not had cancer. These trials use drugs, vitamins or diet to reduce risk of cancer. Some trials are conducted with people who have had cancer and want to prevent the return of cancer (recurrence), or reduce the chance of developing a new type of cancer.

Screening Trials – study ways to detect cancer. They are often conducted to determine whether finding cancer before it causes symptoms decreases the chance of dying from the disease. These trials involve people who do not have any symptoms of cancer.

Diagnostic Cancer Trials – develops new tests or scans

Treatment Trials - studies new drugs or combinations of drugs; new ways of giving treatment, and new types of treatment

Quality of life trials explore ways to improve the comfort and quality of life of cancer patients and cancer survivors. These trials may study ways to help people who are experiencing nausea, vomiting, sleep disorders, depression, or other effects from cancer or its treatment.

Genetics Study Trials – are sometimes part of another cancer clinical trial. The genetics component of the trial may focus on how genetic makeup can affect detection, diagnosis, or response to cancer treatment.

Clinical trials are conducted in 4 phases:

Phase 1 trials look at whether a trial treatment drug is safe or has any harmful effects and attempts to establish the right dosage required.

Phase 2 trials look at the effectiveness of the treatment.

Phase 3 trials test a new treatment against the existing standard treatment. If it yields better results, it may become the new standard treatment.

Phase 4 trials are carried out after a drug has been licensed. They collect information about side effects, safety and the long term risks and benefits of a drug.

Ongoing research attempts to improve mesothelioma treatment options but clinical trials will not all result in new and better treatment. After testing, it may be discovered that the treatment being tested does not work, or that it has worse side affects than existing treatments. But, to researchers and doctors, and in the end for patients, it is crucial to keep this research going.

About Mesothelioma

Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum.

What is the mesothelium?

The mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.

How common is mesothelioma?

Although reported incidence rates have increased in the past 20 years, mesothelioma is still a relatively rare cancer. About 2,000 new cases of mesothelioma are diagnosed in the United States each year. Mesothelioma occurs more often in men than in women and risk increases with age, but this disease can appear in either men or women at any age.

Mesothelioma Symptoms

Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleura are often symptoms of pleural mesothelioma. Symptoms of peritoneal mesothelioma include weight loss and abdominal pain and swelling due to a buildup of fluid in the abdomen. Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, trouble swallowing, or swelling of the neck or face.
These symptoms may be caused by mesothelioma or by other, less serious conditions. It is important to see a doctor about any of these symptoms. Only a doctor can make a diagnosis.

The early symptoms of mesothelioma are often ignored, because they may be caused by a variety of ailments. These symptoms include:

pain in the lower back or at the side of the chest

shortness of breath

difficulty swallowing

cough

fever

fatigue

abdominal pain, weight loss, and nausea and vomiting (symptoms of peritoneal mesothelioma)

Causes of Mesothelioma -

The primary risk factor for developing mesothelioma is asbestos exposure. In the past, asbestos was used as a very effective type of insulation. The use of this material, however, has been declining since the link between asbestos and mesothelioma has become known. It is thought that when the fibers of asbestos are inhaled, some of them reach the ends of the small airways and penetrate into the pleural lining. There the fibers may directly harm mesothelial cells and eventually cause mesothelioma. If the fibers are swallowed, they can reach the abdominal cavity, where they can contribute to the formation of peritoneal mesothelioma.
Exposure to certain types of radiation as well as to a chemical related to asbestos known as zeolite has also been related to incidences of mesothelioma.

Mesothelioma Treatment -

Treatment for mesothelioma depends on the location of the cancer, the stage of the disease, and the patient’s age and general health. Standard treatment options include surgery, radiation therapy, and chemotherapy. Sometimes, these treatments are combined. Surgery is a common treatment for mesothelioma. The doctor may remove part of the lining of the chest or abdomen and some of the tissue around it. For cancer of the pleura (pleural mesothelioma), a lung may be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed.

The most critical form of mesothelioma is the malignant form. Known as malignant mesothelioma, the primary causal factor is asbestos infection. According to the US National Cancer Institute, “Malignant mesothelioma is a disease in which cancer (malignant) cells are found in the sac lining the chest (the pleura), the lining of the abdominal cavity (the peritoneum) or the lining around the heart (the pericardium).”

Mesothelioma can be classified into three types – pleural mesothelioma, peritoneal mesothelioma and pericardial mesothelioma. Pleural mesothelioma refers to a cancer of the lining of the lung (pleura), peritoneal mesothelioma refers to a cancer of the abdominal cavity (peritoneum) lining, and pericardial mesothelioma is a cancer that occurs in the lining that surrounds the heart (pericardium). The subtypes of mesothelioma are of three basic types, one very aggressive, one least aggressive, and one lying between the two extremes.

Malignant mesothelioma can be diagnosed through several imaging techniques. These imaging techniques enable physicians to assess mesothelioma. Once mesothelioma is suspected, patients are advised to undergo several tests, like X-ray, Computed Tomography (CT) scan, Magnetic Resonance Imaging (MRI) scans, and Positron Emission Tomography (PET) imaging. The physician may also like to undertake special mesothelioma tests like thoracoscopy, peritoneoscopy and biopsy.

Learning about the stage of mesothelioma is a critical factor that helps physicians to decide the treatment plan. If the cancer is confined to the pleura, mesothelioma is considered localized. If the cancer spreads beyond the pleura and to other parts of the body such as the lungs, abdominal cavity, lymph nodes and the chest wall, mesothelioma is considered to be in an advanced stage.

The oft used and the oldest system for determining the stages of mesothelioma is the Butchart System. The Butchart System is based on the extent of the primary tumor mass available in a patient. This system divides mesothelioma into four stages. The TNM system, a slightly advanced system over the Butchart System, determines staging through variables of tumor in mass and the spread, the lymph node involvement and metastasis. However, the latest system is known as the Brigham System, where staging is done as per the respectability and lymph node involvement. In spite of such modern techniques, a definitive diagnosis of mesothelioma still remains possible through fluid diagnosis and tissue biopsy.

Mesothelioma is a deadliest form of cancer that has developed via the exposure of asbestos. Mesothelioma develops the malignant or cancerous cells in the mesothelium, which is the cell which protects various internal organs in our human body. The types of mesothelioma are pleural mesothelioma, peritoneal mesothelioma and pericardial mesothelioma. The mesothelioma law resources provide you information on the disease, mesothelioma lawsuits, mesothelioma doctors, and mesothelioma lawyers and other legal resources.

Mesothelioma law resources help a person who has developed the disease in the exposure of asbestos providing the legal resources and further steps for the mesothelioma settlements. Mesothelioma is the disease that damages the cells which surround various internal organs like the heart, lungs and the abdomen. It develops gradually within the human body by damaging the cell lining which covers these organs. Inhaling the asbestos materials from the workplace is a major cause for the development of mesothelioma.

Shortness of breath and chest pain developed due to the accumulated fluid in the pleura are the major symptoms of pleural mesothelioma. Bowel obstruction, abnormality in the clotting of blood, fever and anemia are few of the peritoneal symptoms. The common symptoms of the pericardial mesothelioma are persistent coughing, palpitations, shortness of breath and chest pain.

The person who has developed mesothelioma has to be diagnosed immediately when these symptoms are seen. If the presence of mesothelioma is confirmed, immediate treatment is recommended. The person may seek lawsuit assistance as the legal compensation for the mesothelioma through the exposure of asbestos. A legal medical expert can help you in providing the information of the disease that has developed through the exposure of asbestos. This would help you in receiving rightful and fair compensation.

There are several law firms that offer you the best service. One has to assess whether the law firm to be selected is a good one and certified applicable under the State Bar Association. A perfect lawyer can be approached from any top law firm who has a well specialized track record in dealing with mesothelioma cases. A lawyer with a good track record can offer you with the best compensation for mesothelioma from the irresponsible firms that have failed to protect you from the exposure of asbestos.

Mesothelioma prognosis and mesothelioma treatment options depend on the size of the tumor, the stage of cancer, potential surgical removal of any tumor, amount of fluid in the chest or abdomen, overall health and age of patient, specific type of mesothelioma cancer cell and whether cancerous cells are found anywhere else in the body.

The mesothelioma prognosis is determined through physical examination and the results of a number of medical tests designed to evaluate the rare asbestos cancer. Once a mesothelioma prognosis is finally determined, then treating this aggressive and rare cancer can begin. Early diagnosis and treatment are most important in looking for a favorable mesothelioma prognosis.

Since mesothelioma is usually diagnosed at an advanced stage, the statistics for one to five year survival are usually unreliable.

The two most common types of mesothelioma are peritoneal (abdominal) mesothelioma and pleural (lung) mesothelioma, with pleural mesothelioma being the most common. Peritoneal mesothelioma can be difficult to stage because of its rarity. The initial symptoms of pleural mesothelioma are subtle and often ignored resulting in the cancer being more advanced when it is finally diagnosed causing it to be difficult to stage. However, because it is the most common of the mesothelioma cancers, pleural mesothelioma has multiple staging systems.

Unfortunately, patients who have been diagnosed with peritoneal or pleural mesothelioma are often advised of a grim mesothelioma prognosis, one which can often be less than one year survival expectancy from the time of diagnosis. Of course every patient is so different requires a different mesothelioma treatment plan and as a result of the individuality of each patient, an accurate mesothelioma prognosis must be individualized by your physician.

The mesothelioma prognosis has several important factors such as the patient’s overall health at the time of diagnosis, exact type of mesothelioma tumor, size of the mesothelioma tumor and precise location of the mesothelioma tumor. Normally mesothelioma is located near the vital organs such as the heart and lungs which can cause severe consequences if the cancerous tumors begin to press on these vital organs. It is important to remember that the healthier a patient is going in to treatment for malignant mesothelioma then the patient generally responds better to treatment and has a greater chance of a prolonged survival.

After properly being diagnosed with mesothelioma and a mesothelioma prognosis is made, the doctor and patient will discuss treatment options. Because there is currently no known cure for mesothelioma, treatment options are designed to relieve symptoms, try to prevent metastasis and to prolong life while maintaining an acceptable quality of life.

Mesothelioma is an unusual form of cancer of the mesothelial cells that line the lungs, heart and the stomach. In recent times, in the U.S, there has been an alarming rise in the occurrence of mesothelioma cases mainly caused by exposure to asbestos. Mesothelioma that develops in the lining of the heart is known as pericardium mesothelioma. When found in the sac that lines the chest or abdomen, it is called malignant mesothelioma. Asbestosis is a chronic lung ailment that produces shortness of breath, coughing and even permanent lung damage. Many treatment programs for mesothelioma have been initiated with a purpose of curbing or curing the disease. There are a number of Web sites that provide information on various treatments of mesothelioma.

Mesothelioma treatment depends on many factors that include the various stages of cancer, location, state of cancer, appearance of cancer cells and the patient?s age and requirements. Web sites on mesothelioma provide information on the different types of treatments including traditional care for malignant mesothelioma. This involves surgery that removes the cancer, chemotherapy that uses drugs to fight the cancer, and radiation therapy that uses high-dose x-rays or other high-energy rays to kill cancer cells.

Certain Web sites provide useful articles on experimental therapies for mesothelioma treatments, which include usage of the drug Alimta. They feature articles on various clinical trials and research studies that promise new or experimental mesothelioma treatments. These Web sites list typical treatment strategies based on different stages of mesothelioma.

Generally, Web sites of top cancer centers for mesothelioma treatment are listed alphabetically by state and are of great convenience to patients. People can register themselves online and consult top experts who after verifying their problem through a questionnaire, advice on appropriate drugs that help to cure mesothelioma. Many Web sites also provide information on victims of mesothelioma and their families. Patients of mesothelioma can share their experience with them and get emotional support. On the whole, mesothelioma treatment Web sites offer a great source of information that creates awareness about diverse treatment options available for mesothelioma.

• Cough

• Difficulty sleeping

• Fever

• Pain at the side of the chest or the lower back

• Pleural effusions (fluid in the chest cavity)

• Progressive loss of appetite and weight loss

• Dyspnea

• Tiredness

• Trouble swallowing

• Muscle weakness

• Sensory loss

• Nausea

Pleural effusion is an accumulation of fluid between the lining of the lung and the chest cavity. It is one of most common symptoms of mesothelioma and leads to shortness of breath. As the fluid collects in the lining of the lungs and chest, the pain and shortness of breath also increase. Dyspnea is shortness of breath which can be caused by a pleural effusion and/or by the presence of a tumor in the pleura or the lining of the lungs.

A buildup of fluid in the pleural can create a feeling of fullness and pressure, causing areas of pain in the chest cavity and sometimes in the lower back area. Chest pain occurs more often on the right side of the body, as mesothelioma affects the right lung 60% of the time. Only 5% patients suffer from mesothelioma in both lungs.

In some cases, a patient may also have chronic hoarseness, difficulty swallowing (dysphagia) and/or the coughing up of blood (hemoptysis). These are the rare symptoms of mesothelioma and seen in less than 1% mesothelioma patients. If the patient also suffers from swelling of the face or neck areas, it means that the cancer has spread beyond the mesothelium.

Peritoneal Mesothelioma

The other type of mesothelioma is peritoneal which attacks the lining of the stomach or the abdominal cavity. It can cause symptoms like:

• Belly Pain

• Nausea

• Vomiting

• Weight loss

• Fever

• Night sweats

• Frequency of urination

• Bowel obstruction

Abdominal pain and swelling due to a buildup of fluid in the abdomen also known as ascites is one of the symptoms of peritoneal mesothelioma. If there is a tumor in the peritoneum membrane, it can put increasing pressure on the organs in the abdomen, leading to bowel obstruction and distention.

Pericardial Mesothelioma

The third type of mesothelioma is pericardial mesothelioma which attacks the lining of the chest cavity. It is not a common type of cancer. It can cause symptoms like:

• Heart palpitations

• Chest pains

• Shortness of breath

• Persistent cough

• Weight loss

• Irregular heartbeat

Pericardial effusion may also occur in pericardial mesothelioma. It is the accumulation of liquid in the lining of the chest cavity which may cause difficulty in breathing and shortness of breath. The patient may also complain of irregular heartbeat which is caused due to liquid accumulation in the chest. Persistent cough along with blood may also occur. Pericardial mesothelioma can also lead to lung cancer.

Some of these symptoms can help you identify mesothelioma. Some patients show no symptoms of their mesothelioma which makes it more difficult to diagnose. The exact symptoms will often depend on the area where mesothelioma affects which will help you identify mesothelioma.

Malignant mesothelioma is an uncommon form of cancerous tumors originating in the body tissue known as the mesothelium. The mesothelium is a specialized layer of cells that line and protect many internal organs such as the chest and abdominal cavities.

Types of Malignant Mesothelioma

The first type of malignant mesothelioma is called Pleural Mesothelioma or mesothelioma of the pleura. It is the most common type of mesothelioma making up approximately 75% of all mesothelioma cases. The pleura is a thin serous membrane found between the lungs and the chest cavity that provides a lubricated surface preventing the lungs from chafing against the chest walls. It also serves as a protective layer.

The second most common type of mesothelioma is Peritoneal Mesothelioma, also known as mesothelioma of the peritoneum. The peritoneum is a thin serous membrane that encloses the organs of the abdomen. Peritoneal Mesothelioma is a rare form of malignant mesothelioma cancer. This disease accounts for approximately 10% to 20% of all mesothelioma cases. It tends to be a more invasive form of cancer; patients diagnosed with this disease have a shorter life expectancy than if they had attracted Pleural Mesothelioma.

The third and least common type of mesothelioma is pericardial mesothelioma also known as mesothelioma of the pericardium. It accounts for less than 10% of all mesothelioma cases. The pericardium (heart sac) is the serous membrane that surrounds and protects the heart.

There are about 2,200 new cases of malignant mesothelioma of the visceral pleura each year. Mesothelioma is difficult to diagnose and is rarely curable. The most common symptoms are dyspnea and chest wall pain.

Causes

Asbestos is the predominant cause of malignant mesothelioma of the visceral pleura. The period between the time of exposure to asbestos and the onset of symptoms is about 20 to 50 years. Because of this late onset, it occurs most commonly in the later years of life. It also occurs more often in men than in women.

Diagnosis

Doctors usually make an incision through the chest wall and insert an instrument called a thoracoscope between two ribs to view the area. Doctors will then do a biopsy to select a tissue sample that can be analyzed under a microscope.

Stages of Mesothelioma

Stage I: The cancer is found in the lining of the chest cavity near the lung and heart or in the diaphragm or the lung.

Stage II: The cancer has spread beyond the lining of the chest to lymph nodes in the chest.

Stage III: Cancer has spread into the chest wall, center of the chest, heart, through the diaphragm, or abdominal lining, and in some cases into nearby lymph nodes.

Stage IV: Cancer has spread to distant organs or tissues.

Treatment

Radiation and radiotherapy are used in situations where the cancer is localized at the point of origin.
Chemotherapy is used in more advanced stages of malignant mesotheliomas.

Cytoreductive surgery plus hyperthermic (heated) chemotherapy improves the survival and quality of life for patients with peritoneal metastases (tumors involving the lining of the abdomen).

Surgery is the option used for Stage I malignant mesothelioma. For stages II to IV, treatment by surgery is still evolving.

Mesothelioma is a very rare form cancer inflicting some people. Not all countries report cases of the disease. But did you know that there are reported cases of mesothelioma and granuloma among feline creatures?

Feline granuloma and mesothelioma are much more rare than human mesothelioma. However, experts and researchers are turning more curious and interested about the subject as years go by. That is because there are too many questions and factors that must be resolved and answered about feline cases of granuloma and mesothelioma.

But first, it would be better if you would have a briefer of what granuloma and mesothelioma are. For sure, your interest and curiosity would be further aroused if you find out the known causes for the disease. You might ask the question, ‘How do cats acquire such ailments?’

Granuloma and mesothelioma

In medical terms, granuloma and mesothelioma are two different terms and diseases for living organisms like mammals. To make it simple, there is a clear distinction between the two. Granuloma is non-cancerous or is often described as benign, while mesothelioma in contrast is most of the time malignant, or cancerous, and would often lead to the death of the individual.

While both the diseases affect tissues within the internal organs of the body, there is still basic differences. One, granuloma is considered a form of a serious infection and can easily be treated. Second, granuloma is not as severe as mesothelioma.

For its part, mesothelioma is often malignant and death-causing. Although prognosis, or rate or chances of survival, is possible, most of the reported cases end up in death of the diagnosed patient.

To understand mesothelioma better, try to comprehend its causes and other problems associated with it.

Mesothelioma, in focus

Mesothelioma is a rare form of cancer that occurs in the mesothelial tissue or the sac lining in the chest. Researches have found that asbestos when exposed to air disintegrates into very minuscule fibers that can be inhaled without people being aware of it.

Once the asbestos fibers reach the lungs, they enter the mesothelila tissues and accumulate. The process would not create significant adverse results overnight. Experts estimate that it should take about two months of exposure before a person accumulates sufficient asbestos fibers to develop a tumor that would eventually lead to mesothelioma.

Another striking fact about mesothelioma is that it does not occur in an asbestos-exposed person until about 20 to 30 years after the exposure. That is the main reason why on the average, mesothelioma patients are aged about 50 years to 70 years.

Thus, people exposed to asbestos would not abruptly feel and bear the effects of exposure to the substance until a significant amount of time. That way, in the past, people diagnosed with mesothelioma had not readily linked the disease to their possible exposure to asbestos.

Mesothelioma in cats

Feline mesothelioma, therefore, is another case. Is feline mesothelioma caused by asbestos exposure? If that is so, then the owner of the cat is also at risk of developing mesothelioma in the future because he might also be of exposed to the substance.

In cats, mesothelioma could be disgnosed of the cat is aged seven to ten years. Most common symptom is drastic and sudden loss in weight.

Veterinarians are still researching on what may cause feline mesothelioma and granuloma, although some suggest that it may be caused by substances in cat litter boxes. The dusts in the litter boxes may contain little amount of asbestos, although this ideas is still to be verified.

Often, cats diagnosed with feline mesothelioma or feline granuloma end up dying. That is because animals are hard to treat because of the complexity of their structures. Many vets also ask cat owners with to just let consent for biopsy so the cat could contribute well to current research about feline mesothelioma and granuloma.

Euthanasia is not an issue among sick animals, although animal rights advocates could openly oppose the idea. If your cat is diagnosed with mesothelioma or granuloma and there is only less chance of prognosis, make the decision to donate the cat instead for biopsy. That way, at least the cat died for good purposes.

Mesothelioma is a terrible disease that has a huge latency period. To explain in more detail, latency period refers to the time duration between the exposure to the causative agent and the onset of the disease. The causative agent in the case of this disease is asbestos. The manifestation of indications of this disease is much after exposure to asbestos. Sometimes, this may be even after 20-50 years.

Another notorious characteristic of this disease is that it has symptoms that are very similar to other benign diseases. Many times pleural mesothelioma (lung cancer) is confused with pneumonia and this leads to dire consequences. What happens is that the patient is in the last stages before they even realize they have such a killer disease. Therefore, little can be done to help them the last stages of cancer.

Certain treatments have been devised for mesothelioma. However, these only help to mitigate the painful symptoms. Normally, the spread of the disease cannot be checked. There is no known cure for this disease. The choice of treatment for a mesothelioma patient is based on the stage of mesothelioma that he or she is in.

Stages of Mesothelioma

Butman System

The Butman system is used to define the Mesothelioma staging system. The entire basis of this system is the extent to which the tumor has spread. The various levels of mesothelioma based on this system are as follows:

Stage I: At this stage, the presence of mesothelioma is in the right side or the left side of the pleura (lungs). It may also be in the pericardium or diaphragm. Diaphragm is the muscle that separates the chest and the abdomen. In this stage, mesothelioma is only on one side (left or right) of the pleura.

Stage II: In this degree of mesothelioma, the disease spreads to the other side of pleura or to the esophagus or heart or chest wall or even the lymph nodes.

Stage III: In this phase, the disease is in a serious assaulting phase. It spreads from the diaphragm into the peritoneum. Peritoneum refers to the abdominal cavity lining. While in the previous stage, the lymph modes of the chest may be involved. This stage may involve the lymph nodes beyond the chest too.

Stage IV: This is the final terrible stage of mesothelioma wherein the disease spreads to the other organs through the bloodstream.

TNM staging System

The American Joint Committee on Cancer (AJCC) has developed another new staging system. This TNM staging system is very similar to that used for other types of cancers. In this system T stands for tumor

N stands for the assault on lymph nodes and M stands for metasis.

The staging system is based on the following: § the size of the tumor and the extent to which it has spread to nearby organs § the extent of spread to lymph nodes § the extent of spread to distant organs.

The various degrees of mesothelioma as per the TNM staging system are as follows:

Stage I: The mesothelioma may be in the right or the left pleura. It may also have assaulted the pericardium or the diaphragm on the same side. However, it would not have spread to the lymph nodes.

Stage II: The disease may have spread to the lungs, diaphragm, lymph nodes or pericardium on the same side.

Stage III: In this phase, the mesothelioma may have spread into the muscles of the chest wall, ribs, esophagus, heart and other organs on the same side. It may also have spread further into the lymph nodes on the same side.

Stage IV: In this stage, mesothelioma affects the lymph modes in the chest on the same side or may start spreading to the lungs or pleura on the other side. Also, if mesothelioma is found in the distant organs or if it spreads to organs other than the abdomen and chest, (through the blood stream), it is the fourth stage.

Though the TNM system is more clear and comprehensive, still the Butchart system is popularly used to describe the stages of mesothelioma. Whatever the staging system used, it is important to understand that mesothelioma stage depiction is important for deciding the type of treatment to be used on a patient.

How are the stages of mesothelioma determined?

CAT scans, MRI testing and other tests like x-rays help to determine the stage of mesothelioma in the patient. After this, the doctor informs the patient and his or her family about the level and type of treatment that is required. Mesothelioma has no known cure. So, the doctor can only offer to reduce the symptoms, to mitigate the pain and provide psychological support.

What are the treatments offered to mesothelioma patients?

Chemotherapy, radiation and surgery are the options available for treating a mesothelioma patient. Apart from these traditional treatments, various new ones keep coming up every once in a while. However many are under study and need testing. To avail of them, a patient can undergo a medical trial. In this way, he will benefit the medical research in mesothelioma as well as avail of the new medicine or method of treatment. The health of the patient and the age of the patient will also be considered when deciding the level and type of treatment offered for a patient. While undergoing treatment for mesothelioma cancer, the patient needs not only physical strength but also emotional strength. The patient should be strong at heart to face whatever happens next.
