mesothelioma
a malignant TUMOUR of the PLEURA of the chest cavity and also of the PERICARDIUM or PERITONEUM . It is usually associated with exposure to asbestos dust but may arise independently with no known cause. Most mesotheliomas are in sites that render them inoperable, and CHEMOTHERAPY and RADIOTHERAPY are used but often with limited success.
The tissue that lines your lungs, stomach, heart, and other organs is called mesothelium. Mesothelioma, also known as malignant mesothelioma, is cancer of that tissue. It usually starts in the lungs, but can also start in the abdomen or other organs.
Malignant mesothelioma is rare but serious. Most people who get it have worked or lived in places where they inhaled or swallowed asbestos particles. After being exposed to asbestos, it usually takes a long time for the disease to form.
Symptoms include:
- Trouble breathing
- Cough
- Pain under the rib cage
- Pain, swelling, or lumps in the abdomen
- Weight loss for no known reason
- Blood clots
- Constipation
- Fatigue
Sometimes it is hard to tell the difference between malignant mesothelioma and lung cancer. To find out if you have mesothelioma, your health care provider will likely use a physical exam, imaging tests, and a biopsy.
Malignant mesothelioma is often found when it is advanced. This makes it harder to treat. Treatment options may include:
- Surgery
- Radiation therapy
- Chemotherapy
- Immunotherapy
- Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells
