Mesothelioma Diagnostic Criteria: What You Need to Know

Greetings and welcome to our comprehensive guide on mesothelioma diagnostic criteria. This article aims to provide you with everything you need to know about mesothelioma, including its diagnostic criteria, symptoms, and treatment options. Mesothelioma is a rare but serious form of cancer that usually affects the lungs or chest wall. It is caused by exposure to asbestos, a mineral commonly found in building materials, shipyards, and other industrial settings. With early detection and proper treatment, the prognosis for mesothelioma patients has been improving. However, the key to early detection and proper treatment is knowing the diagnostic criteria for mesothelioma. So, let’s begin!

What Is Mesothelioma?

Mesothelioma is a type of cancer that affects the mesothelium, which is the thin layer of tissue that covers most of our internal organs. Mesothelioma is caused by exposure to asbestos fibers, which can accumulate in the lungs, abdomen or heart. These fibers can damage cells in the mesothelium and eventually lead to cancerous growths.

Mesothelioma Symptoms

The symptoms of mesothelioma may not appear until several years after exposure to asbestos. The most common symptoms include:

Types of Mesothelioma Diagnostic Criteria
Pleural Mesothelioma Presence of pleural effusion or pleural thickening, positive biopsy for mesothelioma cells
Peritoneal Mesothelioma Presence of ascites, peritoneal thickening, positive biopsy for mesothelioma cells
Pericardial Mesothelioma Presence of pericardial effusion, positive biopsy for mesothelioma cells

Diagnosing Mesothelioma

Diagnosing mesothelioma can be a complex process, as the symptoms can be similar to other conditions. The diagnostic criteria for mesothelioma include:

Imaging Tests

Imaging tests such as X-rays, CT scans, and MRI scans can help identify abnormalities in the lungs or abdominal cavity that may indicate mesothelioma. These tests can also help determine the extent of the disease and whether it has spread to other parts of the body.


A biopsy involves removing a small sample of tissue from the affected area for examination under a microscope. This is the most definitive way to diagnose mesothelioma. Biopsies can be performed using a needle, endoscope or surgical procedure.

Blood Tests

Blood tests are not used to diagnose mesothelioma, but they can help determine the overall health of the patient and whether the cancer has spread to other parts of the body. Blood tests can also be used to monitor the effectiveness of treatment.
