The two main types of lung cancer are non-small cell lung cancer and small cell lung cancer, which are named after the type of cell in which the cancer starts.
Non-small cell lung cancer is the more common type, accounting for about 85% of all cases.The most common symptoms of lung cancer include coughing (often with blood), shortness of breath, chest pain, hoarseness, fatigue, and unexplained weight loss. However, these symptoms may not appear until the cancer is advanced.
Smoking is the leading cause of lung cancer, accounting for about 85% of all cases. Other risk factors include exposure to secondhand smoke, air pollution, and occupational exposure to certain chemicals and substances.
Treatment for lung cancer may include surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of these treatments, depending on the stage and severity of the cancer.
