Lung cancer is a serious disease that occurs when abnormal cells in the lungs grow uncontrollably. It is often linked to smoking, but non-smokers can also develop this condition. Symptoms may include a persistent cough, chest pain, and difficulty breathing. Early detection is crucial for better treatment outcomes. There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer. Treatment options vary and may include surgery, chemotherapy, and radiation therapy. Regular check-ups and avoiding smoking can help reduce the risk of developing lung cancer, making awareness and prevention important for everyone.
