A physician can conduct a comprehensive medical history and physical examination to look for symptoms and risk factors related to mesothelioma. Shortness of breath, lower back pain, pain underneath the rib cage, abdominal swelling, hoarseness, and coughing up blood can be symptoms of mesothelioma. Asbestos exposure is a common risk factor for developing this cancer.
A chest x-ray photographs organs and bones inside the chest. This picture can show abnormalities of the pleura - the membrane that covers the lungs and lines the walls of the chest - which may assist in detecting mesothelioma. Computer tomography (CT) scans, positron emission tomography (PET) scans, and magnetic resonance imaging (MRI) scans are imaging tests that can offer additional information about the presence and severity of mesothelioma.
Mesothelioma can also be diagnosed through fluid tests and tissue samples. A biopsy can remove cells and/or tissues from the pleura to help determine whether they are cancerous.
