A peritoneal mesothelioma diagnosis cannot be made on the basis of symptoms alone. The process begins with a thorough examination of a patient’s medical history and physical condition, followed by sophisticated diagnostic testing such as imaging and fluid and tissue tests.
Imaging tests such as x-rays or CT scans are used to detect any abnormalities in the body and a biopsy is usually performed to confirm that the cancer involved is indeed mesothelioma. A biopsy is a minor surgical procedure that involves the removal of fluid or tissue from the peritoneum.
After the biopsy, the fluid and tissue is tested in a laboratory for the presence of mesothelioma cells. If the biopsy returned reveals that a patient has peritoneal mesothelioma, the doctor, together with the patient, will detail a treatment plan.
