Malignant Mesothelioma
Malignant Mesothelioma is a rare cancer in which malignant or cancerous cells form in the thin layers of tissue lining the human chest, heart or abdomen. When the cancer is in the chest, it affects the pleura or tissue lining the lungs and is called malignant pleural mesothelioma. This is the most common type of mesothelioma.
Although there is now a growing awareness of the hazards of asbestos to health, still many have not heard of Mesothelioma and thus, have not understood its nature, cause, signs and treatment. Even some physicians find it hard to detect Mesothelioma because its symptoms are akin to other diseases like lung cancer and pneumonia. Furthermore, it takes decades for a patient who was exposed to asbestos to develop Mesothelioma — fifty years, at most.
The majority of malignant mesotheliomas occur in people who have been exposed to asbestos, either directly or via people they live with. Avoiding exposure to asbestos can largely prevent malignant mesotheliomas.
Malignant mesothelioma is the most common form of the disease. This type of mesothelioma can be further classified into the location where the malignant tumor arises or the type of cancer cells produced. Classification into the location of the cancer gives three types of mesothelioma cancer:
(i) Pleural mesothelioma: this arises in the protective lining and the cavity of the lungs. Most of the symptoms associated with it arise due to the build-up of fluid between the chest cavity and the lining of the lungs (called pleural effusion). This results in difficulty in breathing, shortness of breath, persistent coughing, coughing up of blood and fever. This is the most common form of mesothelioma cancer representing 75% of all cases (ii) Peritoneal mesothelioma: this is the development of cancer in the stomach and the abdomen. The cancer usually starts in the abdominal area and spreads to other parts of the body. Symptoms are due to the pressure of the tumor on the stomach and the abdomen, causing abdominal pain, swelling, loss of appetite, vomiting, breathing problems, anemia and a host of other symptoms. Peritoneal mesothelioma accounts for 10-20% of mesothelioma cases.
Stage III Mesothelioma means that the malignant cells have already spread to the chest wall, esophagus and the lymph nodes on one part of the chest. The patient may suffer severe pain near the parts affected. When not treated immediately or when the Mesothelioma patient doesn’t respond well to medication, the cancer may advance to the fourth stage. The fourth stage Mesothelioma is formidable since at this stage the Mesothelioma cells have penetrated into the bloodstream and other organs in the body like the liver, the bones and the brain. The lymph nodes on the other side of the chest may also be affected by Mesothelioma in stage IV.
Depending on the stage, a treatment plan may include surgery, radiation therapy or chemotherapy. Some cancer treatment centers are involved in clinical trials using biotherapy and immunotherapy.
