Diagnosing Mesothelioma: What You Need to Know

Mesothelioma is a type of cancer that affects the mesothelium, a thin layer of tissue that covers most of the body’s internal organs.

Diagnosing mesothelioma can be challenging, but there are steps doctors take to identify the disease:

Medical history: Doctors will ask about your past exposure to asbestos, as this is the main cause of mesothelioma.

Physical exam: A doctor will examine you for any signs of mesothelioma, such as fluid buildup in the chest or abdomen.

Imaging tests: These include X-rays, CT scans, and MRIs, which can help detect abnormalities in the body.

Biopsy: During a biopsy, a small sample of tissue is removed from the affected area, typically the lining of the lungs, abdomen, or heart, where mesothelioma commonly develops. This tissue sample is then examined under a microscope by a pathologist to determine if cancer cells are present. Biopsies are essential for accurately diagnosing mesothelioma and determining its type and stage, which in turn guides treatment decisions. There are different types of biopsies used in mesothelioma diagnosis, including needle biopsy, thoracoscopy, laparoscopy, and surgical biopsy, each with its own advantages and considerations based on the individual’s circumstances.

Blood tests: While there is no specific blood test for mesothelioma, certain markers may be elevated in people with the disease.

If mesothelioma is suspected, further tests may be needed to determine the extent of the cancer and plan the best course of treatment. Early detection and diagnosis are crucial for improving outcomes for people with mesothelioma. If you have any concerns about mesothelioma or have been exposed to asbestos in the past, it’s important to talk to your doctor.
