Mesothelioma is a rare cancer that develops in the mesothelium, which lines the body’s internal organs. It usually occurs after exposure to asbestos. The disease has been linked to working in factories where asbestos was used, living near an asbestos mine, or being exposed to asbestos dust at home.
The most common type of mesothelioma is called epithelioid mesothelioma.
Epithelioid mesothelial cell carcinoma (EMC) is the most common form of mesotheliomas. This type of cancer starts in the mesothelia, which line the lungs, abdomen, and chest cavities. EMC is often found in people who were exposed to asbestos.
Other types include sarcomatoid mesothelioma and biphasic mesothelioma (also known as mixed).
There are two main types of mesothelioma: epithelioid and sarcomatoid. Sarcomatoid mesothelial cell carcinomas are more aggressive than epithelioid tumors. Biphasic mesotheliomas are rarer forms of mesotheliomata.
Mesothelioma is often diagnosed late because it takes time for symptoms to appear.
Symptoms of mesotheliomas usually start with shortness of breath, chest pain, cough, weight loss, fever, fatigue, and abdominal discomfort. These symptoms can occur months or even years before diagnosis.
Symptoms may include chest pain, shortness of breath, coughing up blood or fluid, weight loss, fever, fatigue, nausea, vomiting, abdominal swelling, and back pain.
Mesotheliomalike cancer is not contagious. It does not spread through contact with bodily fluids such as saliva, sweat, tears, urine, feces, vomit, semen, vaginal secretions, breast milk, or blood.
Diagnosis usually involves a CT scan of the chest and abdomen.
There are two main types of mesothelioma: epithelioid and sarcomatoid. Epithelioid mesothelioma is more common than sarcomatoid mesothelioma. Sarcomatoid mesothelial tumors are rarer and tend to occur in younger people.
