Mesothelioma is a disease that affects the lining of the organs, called the mesothelium. Tumors that grow on the mesothelium are often located in the chest, around the lungs or heart. The growths can be either cancerous or benign. People who work with asbestos, a material commonly found in old buildings, have a higher risk of developing mesothelioma. Diagnosis of the disease involves recounting symptoms and medical history as well as undergoing medical testing.
Step 1
Discuss your symptoms with your doctor. Symptoms of mesothelioma can include chest or back pain, breathing difficulties, fever, sweating, coughing, feeling more tired than normal and muscle weakness. Review your medical history with your doctor if you have been exposed to asbestos at work or elsewhere, as asbestos exposure is a primary cause of mesothelioma.
Step 2
Undergo imaging tests that show your internal organs in detail. Chest X-rays may be taken, and CT, MRI or PET scans may be performed to locate the tumors. The exact diagnostic tools used may depend on your symptoms and medical history.
Step 3
Have your blood tested as part of the diagnostic process. The American Cancer Society explains that people with mesothelioma may have elevated levels of substances called osteopontin and SMRP in their blood.
Step 4
Give tissue and fluid samples to confirm a diagnosis of mesothelioma. If suspicious areas are seen on an MRI or CT scan, a biopsy may be the definitive diagnostic tool. Biopsies may be performed in the doctor's office or in the hospital as a surgical procedure.
