Imaging Scans
Most people initially undergo a basic chest X-ray to check for any abnormalities. If an abnormal growth is detected, doctors will recommend a more detailed imaging scan such as a PET scan, CT scan or MRI.
Biopsies
If cancer is suspected, doctors will recommend taking a sample of tissue, also knowns as a biopsy. Doctors use this tissue sample to definitively confirm the presence of mesothelioma cells.
Blood Tests
Blood tests are also available, but they do not confirm the presence of mesothelioma. Research and development is underway to determine if blood tests can aid in early diagnosis for at-risk former asbestos workers.
Staging
There are at least five staging systems doctors use to stage pleural mesothelioma. The most widely used is the IMIG staging system. There are currently no universal staging systems for the cancer's other types.
