Mesothelioma is a rare cancer where cells of the abdomen or chest begin to abnormally multiply. The cancer cells are located in the pleura, the layer of tissue that covers the lungs and lines the chest cavity, or the peritoneum, the tissue that covers the organs and lines the abdomen.

Exposure to asbestos is one of the biggest risk factors for mesothelioma. Living with someone who works near asbestos also increases one’s risk for the disease.

Symptoms of mesothelioma include trouble breathing, pain under the rib cage, pain or swelling in the abdomen, lumps in the abdomen and random, rapid weight loss.

Diagnosis of mesothelioma includes a physical exam, analysis of family medical history, a chest x-ray, complete blood count and/or a biopsy. Treatment is based on the stage and size of cancer. Treatment options include surgery, radiation therapy, chemotherapy and biologic therapy.
