Mesothelioma X-Ray

The Role of X-Ray in Mesothelioma Diagnosis

X-ray imaging is an integral part of a pleural mesothelioma diagnosis. A chest X-ray is one of the most common initial tests for anyone experiencing difficulty breathing, chronic cough or other symptoms affecting the lungs. A mesothelioma chest X-ray can provide important information needed for diagnosis.

As with lung cancer, guidelines recommend an urgent chest X-ray for anyone with signs and symptoms of pleural mesothelioma. Chest X-rays are also a key part of screening tests for those at risk for mesothelioma. Regular chest X-rays can detect changes over time, making them extremely useful for finding early signs of disease.

Mesothelioma imaging scans play an essential role in finding tumors and determining the stage of the disease. But X-ray imaging has some limitations when it comes to diagnosing mesothelioma. A tumor biopsy is needed to confirm a diagnosis.

Mesothelioma Staging With X-Rays

Mesothelioma X-ray imaging has limited usefulness for staging this cancer. Staging is based on the size, number and location of tumors, as well as whether lymph nodes are involved or metastatic tumors are present. X-rays can’t always help identify microscopic tumors. 

They can show pleural effusions, larger tumors and other abnormalities around the lungs. Other asbestos-related abnormalities in and around the lungs include interstitial lung disease and pleural plaques. These block parts of the chest and make it hard to see the anatomy clearly.

Doctors use computer-based 3D imaging to find small tumors and see details outside the lungs. Computed tomography scans usually stage mesothelioma because they create cross-sectional 3D images of the whole body. CT scans help spot tumors, fluid buildup and other problems. Magnetic resonance imaging and positron emission tomography scans also provide useful information for staging mesothelioma.

The first test for a patient with, symptoms related to mesothelioma will be going to their primary doctor, getting an x-ray or a CAT scan done. Based on the results from that, they may go through further testing such as a thoracentesis or paracentesis, which is where they drain fluid, whether it’s from the lining of the lungs or the peritoneal area, which is the abdominal area. The next step would be for a biopsy. The biopsy is a step where they confirm the diagnosis.


This sample is sent to a pathologist who ultimately tests the sample taken out from the tumor and identifies it as mesothelioma.

Mesothelioma X-Ray Findings

Mesothelioma often causes changes visible on X-rays, but these changes can also occur with other conditions like lung cancer. Signs of mesothelioma on X-rays include a collapsed lung, fluid buildup around the lungs, thickened pleura, tumors or masses, pleural plaques and blockages like a tumor blocking an airway.

Survivor Mavis N. tells us that after fluid was found around her lung on a chest X-ray, “They rushed me into the hospital and drained the fluid and tested it.” This process eventually led to her diagnosis of pleural mesothelioma.

In some cases, mesothelioma and other tumors are discovered during routine X-rays or X-rays taken for unrelated reasons. Mesothelioma survivor Barry Knowles tells us he had a chest X-ray after falling from a tree. While the X-ray showed multiple cracked ribs, he says doctors also noticed an “ominous shadow” which was later diagnosed as mesothelioma.

Emerging Technologies in Mesothelioma X-Rays

New advances in X-ray technology are helping improve how doctors diagnose cancer and develop treatments for mesothelioma. These include innovative X-ray techniques like dark-field radiography and photodynamic therapy.

X-ray dark-field radiography is an emerging imaging method that uses less radiation than traditional X-rays while capturing clearer and more detailed images. Researchers are currently studying how well it works to diagnose various lung diseases.

Photodynamic therapy uses light to activate compounds injected into the body. These compounds produce reactive oxygen that kills cancer cells. Doctors focus light on the tumor to destroy cancer cells without harming nearby tissue. A newer method, X-PDT, uses X-rays instead of light. Because X-rays pass through the body, this method can treat deep tumors. Low-dose X-rays help target cancer cells while protecting healthy tissue and reducing radiation exposure.

Commonly Asked Questions About X-Rays

Can X-rays distinguish between different types of mesothelioma?

No, X-rays can identify tumors and other abnormalities, but they can’t determine the cell type of a tumor or where it originated. 

Both pleural mesothelioma and pericardial mesothelioma occur primarily in the chest, but peritoneal mesothelioma can also spread to the chest. Likewise, pleural mesothelioma can cause tumors in the peritoneum. A biopsy is needed to identify the cell type and confirm a mesothelioma diagnosis.

Are mesothelioma X-rays the only imaging technique used for diagnosis?

No. Other types of imaging, including ultrasound, CT, MRI and PET scans, are also used to diagnose mesothelioma. Each type of scan has different strengths and limitations, making them useful for different purposes. For example, CT scans are commonly used in mesothelioma staging, while X-rays are less useful for staging.

What are the limitations of X-rays in detecting mesothelioma?

X-ray images only provide a two-dimensional image with limited detail. Because of this, other abnormalities may obscure some X-ray findings. Other types of scans for mesothelioma can provide greater detail. Computer-assisted scans, such as CT, MRI and PET scans, can produce very detailed 3D images of the body. These scans can also capture images of the entire body at one time, unlike X-rays, which are limited to one area of the body at a time.

How do mesothelioma X-ray findings influence treatment options?

Mesothelioma chest X-rays can help guide treatment to a certain extent. Chest X-rays can identify the location of tumors, obstructions and other abnormalities in the lungs. This can indicate whether a patient needs a chest tube to drain fluid around the lungs and which structures in the lungs mesothelioma is affecting.

Factors such as the presence of pleural effusion, location of tumors and other changes in the lungs help determine which mesothelioma treatment options are best for an individual patient. However, the mesothelioma stage, pathology testing from tumor biopsies and the patient’s overall health are the main factors that help determine the best treatment option.
