Understanding The Different Types of Mesothelioma

Mesothelioma is a rare and aggressive form of cancer that forms in the lining of the lungs, abdomen, or heart. The condition is due to asbestos and has no known cure and has a very poor prognosis. A Mesothelioma lawyer from Williams Kherkher reveals that this type of cancer develops slowly and will not show symptoms until it has developed in the body. In this article, we shall discuss the different types of mesothelioma.

Type According to Location

As to location, there are three types of meosothelioma namely pleural, peritoneal, and pericardial. In pleural mesothelioma, the asbestos fibers start in the tissues that cover the lungs. Its signs and symptoms include:

  • Chest pain under the rib cage
  • Painful coughing
  • Shortness of breath
  • Unusual lumps of tissue under the skin of the chest
  • Unexplained weight loss

Peritoneal mesothelioma takes place in the tissues of the abdomen. Its signs and symptoms include:

  • Abdominal pain
  • Abdominal swelling
  • Lumps of tissue in the abdomen
  • Unexplained weight loss

Pericardial mesothelioma is a rare cancer caused by asbestos fibers getting lodged in the pericardium, the lining around the heart cavity. Most common symptoms include heart attack, nausea, pain in the chest, and shortness of breath

According To Cell Type

Mesothelioma can also be characterized according to the type of cell that makes up the tumor. They are classified into three types which are epithelial, sarcomatoid, and biphasic. The most common cell type accounting for 50 – 75 percent of all diagnosed cases yearly is epithelial mesothelioma. They are uniform in shape, has an elongated pattern, and are adeonocarcinomas. They are easily distinguishable when viewed under high magnification.

Sarcomatoid mesothelioma accounts for 7 to 20% of cases diagnosed yearly. They arise from supportive structures such as muscles and bones.

Finally, biphastic mesothelioma is a combination of epithelial and sarcomatoid cell types. Treatment options may vary but sarcomatoid types are more difficult to treat as it involves surrounding tissues.
