Lung Cancer

Lung cancer is a type of cancer that begins in the lungs. It occurs when abnormal cells grow uncontrollably and can form a tumor, potentially affecting breathing and spreading to other parts of the body. The two main types are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

In its early stages, lung cancer may cause few or no noticeable symptoms. As it progresses, symptoms may include a persistent or worsening cough, coughing up blood, chest pain, shortness of breath, unexplained weight loss, fatigue, or recurrent respiratory infections. These symptoms can also occur with other conditions, so persistent or unusual changes should be medically evaluated.

Smoking is the most important preventable risk factor for lung cancer, although lung cancer can also occur in people who have never smoked. Other risk factors include exposure to secondhand smoke, radon, certain workplace substances, air pollution, and a family history of lung cancer.

Treatment depends on the type and stage of lung cancer and may include surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, or a combination of treatments. Supportive and palliative care may also help manage symptoms and improve quality of life.
