Pericardial mesothelioma is an extremely rare form of cancer that affects the lining around the heart, known as the pericardium. It is primarily caused by exposure to asbestos fibers, and symptoms may not appear until decades after exposure. Recognizing these symptoms early is crucial for timely diagnosis and effective treatment. Below are the common symptoms associated with pericardial mesothelioma:
Chest Pain
One of the hallmark symptoms of pericardial mesothelioma is chest pain. The pain may be sharp, stabbing, or dull and is typically felt in the chest behind the breastbone (sternum). It can worsen with movement, deep breathing, or lying down (orthopnea).
Irregular Heartbeat (Arrhythmia)
Pericardial mesothelioma can cause disruptions in the normal rhythm of the heart, leading to palpitations or irregular heartbeats (arrhythmias). These irregularities may manifest as a fluttering sensation in the chest or a sensation of skipped beats.
Difficulty Breathing (Dyspnea)
As pericardial mesothelioma tumors grow and spread within the pericardium, they can compress the heart or its surrounding structures, leading to difficulty breathing (dyspnea). This shortness of breath may worsen with physical activity or when lying down.
Fatigue or Weakness
Patients with pericardial mesothelioma often experience persistent fatigue or a general feeling of weakness. This fatigue may be exacerbated by the strain on the heart and the body’s immune response to the cancer.
Persistent Cough
Some individuals with pericardial mesothelioma may develop a persistent dry cough that does not respond to typical treatments. This cough may occur due to irritation of the nerves surrounding the pericardium or as a result of fluid buildup around the heart (pericardial effusion).
Recognizing these symptoms and seeking medical evaluation promptly is crucial for early diagnosis and initiating appropriate treatment for pericardial mesothelioma. If you or someone you know is experiencing any of these symptoms—especially with a history of asbestos exposure—it is essential to consult a healthcare professional specialized in mesothelioma care.
