How To Detect Mesothelioma?

Mesothelioma tests include imaging scans, such as chest X-rays and CT scans, blood tests and a biopsy. If a patient shows mesothelioma symptoms, a doctor will conduct a physical exam to check for abnormalities and refer the patient to an oncologist for testing.

What Steps Lead to a Mesothelioma Diagnosis?

1) Symptoms: Symptoms of mesothelioma cause the patient to visit their primary care physician or a hospital for testing.
2) Mesothelioma Testing: The most common first tests are radiology exams such as chest X-rays and CT scans of the chest or abdomen. These initial tests reveal abnormal results, which lead to further.
3) Confirm Diagnosis: The surgeon or oncologist uses a combination of imaging scans, blood tests and biopsies to confirm a mesothelioma diagnosis. A blood test or radiology scans alone cannot confirm a diagnosis of mesothelioma.

There is no clear path to a mesothelioma cancer diagnosis for every patient.

Because the disease is rare and has symptoms similar to other more common and less serious conditions, doctors sometimes confuse it for a different illness or another type of cancer. It is common for patients to be initially misdiagnosed with other conditions before receiving a mesothelioma diagnosis. Pleural mesothelioma can be misdiagnosed as pneumonia or lung cancer, and peritoneal mesothelioma may be misdiagnosed as a more common abdominal cancer.

Providing your doctor with a comprehensive work history is important to the diagnostic process. Doctors are unlikely to suspect the disease unless a patient describes a former job where asbestos exposure may have occurred. Usually, mesothelioma occurs 20-50 years after the initial asbestos exposure.

Researchers are working on ways to detect mesothelioma earlier and with less invasive tools. According to a 2020 review authored by mesothelioma expert Dr. Harvey Pass and others, the potential to diagnose mesothelioma with a breath test might be a reality in the near future.

How to Test for Mesothelioma?

Mesothelioma testing commonly includes imaging scans, biopsies and blood tests. Imaging scans like X-rays and CT scans identify mesothelioma tumors. A biopsy is the only definitive way to confirm a mesothelioma diagnosis. Mesothelioma blood tests are used to measure treatment response.

Imaging tests performed by radiologists reveal the location and extent of mesothelioma tumors. The “gold standard” for mesothelioma imaging is a combination CT-PET scan.

Imaging Tests Commonly Used in Mesothelioma Diagnosis.

X-Rays: Produce basic images of areas with various densities, such as tumors or fluid, within the body.
CT Scans: Also known as CAT scans. These use computer software to integrate hundreds of fine X-ray images to create detailed images of internal structures. These images are much more precise than regular X-rays.
MRIs: Using electromagnetic technology, MRIs generate precise images, which are especially useful when looking at bone, nerve and brain tissue.
PET Scans: These are CT scans where the patient receives an intravenous dose of radioactive glucose, which makes inflamed cells light up on scans. Cell inflammation may be caused by an infection or rapid growth, which could be a sign of cancer.

Mesothelioma Biopsies.

Biopsies are the only way to confirm a mesothelioma diagnosis. The most accurate biopsy technique for mesothelioma is called a thoracoscopy.

Thoracoscopy: While under general anesthesia, the surgeon inserts a small camera between the ribs to suction out the fluid, examine the appearance of the inside of the chest and take biopsies.
Mediastinoscopy: Also under general anesthesia, the surgeon inserts a small camera at the base of the neck to obtain biopsies of the lymph nodes around the windpipe.
Thoracentesis: Under local anesthesia and usually using an ultrasound probe, a small needle is inserted between the ribs in the back to remove pleural fluid buildup around the lungs. It is used to diagnose the cause of pleural effusions.
Fine-Needle Aspiration: Under local anesthesia, a small needle is inserted between the ribs to sample or biopsy tumors while the patient is in the CT scan machine.
Endobronchial Ultrasound-Guided Biopsy: According to a 2016 study, this type of biopsy is helpful at diagnosing pleural mesothelioma when other biopsy techniques can’t obtain a tumor sample.

Mesothelioma blood tests, biomarkers and immunohistochemical markers are not accurate enough to diagnose the cancer alone. They are helpful at monitoring response to treatment.
