Which are the symptoms of Mesothelioma?

Symptoms of Mesothelioma

Mesothelioma is a rare and aggressive form of cancer that primarily affects the lining of the lungs, but can also occur in the lining of the abdomen, heart, or testicles. It is primarily caused by exposure to asbestos, a naturally occurring mineral that was widely used in various industries until its harmful effects were discovered.

The symptoms of mesothelioma can vary depending on the location of the cancer and the stage of the disease. It is important to note that these symptoms may not appear until several decades after asbestos exposure, making early detection and diagnosis challenging.

Pleural Mesothelioma (Lungs)

Pleural mesothelioma is the most common form of the disease, accounting for about 75% of all cases. The symptoms associated with pleural mesothelioma include:

• Chest pain: Persistent and dull chest pain that may worsen with deep breathing or coughing.


• Shortness of breath: Difficulty breathing or feeling breathless, even during light physical activity.


• Persistent cough: A chronic cough that may produce blood or sputum.


• Fatigue: Unexplained and persistent fatigue or weakness.


• Unintentional weight loss: Significant and unexplained weight loss without changes in diet or exercise.

Peritoneal Mesothelioma (Abdomen)

Peritoneal mesothelioma affects the lining of the abdomen and accounts for about 20% of all cases. The symptoms associated with peritoneal mesothelioma include:

• Abdominal pain: Persistent and severe abdominal pain or discomfort.


• Abdominal swelling: Swelling or fluid buildup in the abdomen, also known as ascites.


• Changes in bowel habits: Diarrhea, constipation, or other changes in bowel movements.


• Nausea and vomiting: Persistent nausea and vomiting, often accompanied by loss of appetite.


• Unexplained weight loss: Significant and unexplained weight loss without changes in diet or exercise.

Pericardial Mesothelioma (Heart)

Pericardial mesothelioma affects the lining around the heart and is extremely rare, accounting for less than 1% of cases. The symptoms associated with pericardial mesothelioma include:

• Chest pain: Persistent and sharp chest pain that may worsen with deep breathing or coughing.


• Heart palpitations: Irregular or rapid heartbeat.


• Shortness of breath: Difficulty breathing or feeling breathless, even during rest.


• Fatigue: Unexplained and persistent fatigue or weakness.

Testicular Mesothelioma

Testicular mesothelioma is the rarest form of the disease, accounting for less than 1% of cases. The symptoms associated with testicular mesothelioma include:

• Testicular lump or swelling: A painless lump or swelling in the testicles.


• Testicular pain: Dull or sharp pain in the testicles.


• Hydrocele: Accumulation of fluid in the scrotum, causing swelling.

It is important to remember that these symptoms can also be caused by other, less serious conditions. However, if you have a history of asbestos exposure or suspect you may have been exposed, it is crucial to consult a healthcare professional for a proper diagnosis.

Early detection of mesothelioma can significantly improve treatment options and outcomes. If you or a loved one experience any of these symptoms, especially in the context of asbestos exposure, it is essential to seek medical attention promptly.
