Lung cancer is a type of cancer that develops in the cells of the lungs. It is the leading cause of cancer-related deaths worldwide, and it is responsible for more deaths than any other type of cancer.
Introduction
There are two types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most common type of lung cancer, accounting for about 85% of cases. SCLC is less common and tends to grow and spread more quickly than NSCLC.
The most common cause of lung cancer is smoking, which is responsible for about 80% of lung cancer cases. Other risk factors include exposure to secondhand smoke, air pollution, radon gas, asbestos, and other chemicals.
Symptoms of lung cancer may include coughing, chest pain, shortness of breath, fatigue, unexplained weight loss, and recurrent infections such as bronchitis or pneumonia.
Treatment options for lung cancer depend on the type and stage of the cancer, as well as the overall health of the patient. Common treatments may include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. It is important to talk to a healthcare professional about the best treatment options for your specific situation.
