Browsing: Lung Cancer

Lung cancer is one of the most common and serious types of cancer, characterized by the uncontrolled growth of abnormal cells in one or both lungs, typically in the cells lining the air passages. The abnormal cells do not develop into healthy lung tissue; instead, they divide rapidly and form tumors that can interfere with the functioning of the lung, which can make it difficult to breathe and spread to other parts of the body. There are two main types of lung cancer: non-small cell lung cancer (NSCLC), which is the most common and includes adenocarcinoma, squamous cell carcinoma, and large cell carcinoma, and small cell lung cancer (SCLC), which is less common but more aggressive and likely to spread quickly. The primary cause of lung cancer is smoking, although non-smokers can also develop lung cancer, often due to exposure to radon gas, secondhand smoke, or other environmental factors. Symptoms may include coughing, chest pain, weight loss, and shortness of breath. Treatment options vary depending on the type and stage of cancer and may include surgery, radiation therapy, chemotherapy, targeted therapy, or a combination of these. Early detection significantly improves the effectiveness of treatment and the overall prognosis.
