Pleural mesothelioma is a type of cancer that develops in the thin layer of tissue surrounding the lungs, known as the pleura. 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 pleural mesothelioma:
Painful Coughing
One of the early symptoms of pleural mesothelioma is a persistent and sometimes painful cough. This cough may initially be dry but can later produce sputum or blood (hemoptysis). The cough may worsen over time as the cancer progresses and the pleura becomes more irritated.
Difficulty Breathing (Dyspnea)
As pleural mesothelioma tumors grow and spread across the pleural lining, they can restrict lung expansion and impair breathing. This leads to increasing difficulty in breathing, especially during physical activity. Patients may experience a sensation of breathlessness or a feeling of tightness in the chest.
Chest Pain Under the Rib Cage
Many individuals with pleural mesothelioma experience persistent chest pain, often felt under the rib cage or in the lower back. This pain may be dull or sharp and can worsen with deep breathing, coughing, or physical exertion. It occurs due to the irritation and inflammation of the pleura caused by the cancerous growth.
Lumps of Tissue Under the Skin on the Chest
In rare cases, pleural mesothelioma can cause visible lumps or nodules to form under the skin on the chest. These lumps may be firm to the touch and are caused by the growth of mesothelioma tumors spreading to the chest wall or nearby lymph nodes.
Unexplained Weight Loss
Significant and unintentional weight loss is a common symptom of pleural mesothelioma. Despite maintaining normal eating habits, patients may lose weight due to the body’s response to the cancer and the metabolic changes associated with advanced disease.
Fatigue or Weakness
Pleural mesothelioma can cause persistent fatigue or weakness, which may significantly impact daily activities and quality of life. This fatigue is often related to the body’s immune response to the cancer, as well as the physical toll of managing symptoms such as pain and difficulty breathing.
Recognizing these symptoms and seeking medical evaluation promptly is essential for early diagnosis and initiating treatment. If you or a loved one is experiencing any of these symptoms—especially with a history of asbestos exposure—consult a healthcare professional familiar with mesothelioma care.
