What is Mesothelioma Disease and its diagnosis

Mesothelioma Disease

Mesothelioma disease is one of the deadliest diseases known to man; the average life span of an inflicted person from the time of diagnosis until death is less than 24 months. It's a disease that strikes approximately 3,000 United States citizens each and every year; hard working people who have labored for a lifetime to provide for their families, doing the work that keeps this country running and a great place to live.

The diseased defined Mesothelium is the protective tissue that covers the chest cavity, abdominal cavity and the cavity around the heart and also produces a special lubricating fluid that allows the internal organs of the body to move around. Malignant Mesothelioma disease can be defined as the cancer of the mesothelial cells which become abnormal and start dividing without any order. These cells also cover the outer surface of most internal organs. The tissue formed by these cells is called mesothelium. The mesothelium helps protect the organs by producing a special lubricating fluid that allows organs to move around. For example, this fluid makes it easier for the lungs to move inside the chest during breathing. Majority of the mesothelioma patients have a prior history of exposure to asbestos.

In the localized stage, the cancer is found in the lining of the chest cavity or in the diaphragm or the lung. Advanced malignant Mesothelioma disease can again be divided into 3 stages namely stage II, III and IV. In stage II, the cancer spreads beyond the chest lining to lymph nodes and in stage III it spreads into chest wall, center of the chest, heart, through the diaphragm or abdominal lining, etc. The final or the fourth stage is the one in which the cancer has already spread to distant organs.

The cancer affecting the lining of the abdomen (peritoneum) is called the peritoneal mesothelioma and that affecting the “sac like” space around the heart (pericardial cavity) is called the pericardial mesothelioma. Mesothelioma at times also affects the covering layer of the testicles. However, the last two types of cases are quite rare. The tumors of the mesothelium can either be benign (non cancerous) or malignant (cancerous). So whenever there are symptoms like shortness of breath, pain in chest/abdomen or swelling in the abdomen, you should consult your doctor immediately.

Diagnosis

After the initial X-rays and scans, the doctor may look inside the chest cavity (in case of pleural tumor) with an instrument called thoracoscope and the test is called thoracoscopy. In case of tumor in peritoneum the doctor may go for peritoneoscopy with the help of a tool called peritoneoscope. Finally, if the abnormal tissue is found then a biopsy is done, whereby a piece of the unnatural tissue is cut out and placed under microscope for examination. After the confirmed diagnosis of Mesothelioma disease it is also essential to ascertain its stages i.e. whether it is in localized stage or in advanced stage.Depending on the stage of the cancer, its location and the health, age and medical history of the patient, 3 types of treatments are mated out to malignant Mesothelioma patients – surgery (to remove the tumor), radiation therapy (application of high energy rays) and chemotherapy (usage of combination of drugs). This apart, if there is any accumulation of fluid in the chest or abdomen, then the doctor needs to drain it out and the process is regarded as thoracentesis and paracentesis respectively. So be aware of the disease, such that you can prevent it at the very onset.
