What is Lung cancer

Lung cancer is a type of cancer that starts in the lungs. It occurs when abnormal cells in the lungs grow out of control, forming a tumor. These cancerous cells can invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system.

Lung cancer is the leading cause of cancer-related deaths worldwide, primarily due to late-stage diagnosis and limited treatment options. It is often associated with long-term smoking, but non-smokers can also develop lung cancer.

Common symptoms of lung cancer include persistent cough, chest pain, shortness of breath, hoarseness, weight loss, and recurring respiratory infections. However, these symptoms may vary depending on the stage and type of lung cancer.

Early detection and timely treatment are crucial for improving lung cancer outcomes. Diagnosis involves imaging tests, biopsies, and other diagnostic procedures to determine the stage and extent of the cancer. Treatment options include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy, depending on the specific characteristics of the cancer.

Prevention of lung cancer involves avoiding tobacco smoke, including secondhand smoke, and reducing exposure to environmental carcinogens such as radon, asbestos, and air pollution. Quitting smoking and adopting a healthy lifestyle can significantly reduce the risk of developing lung cancer.
