Lung Cancer

Lung cancer is one of the leading causes of cancer-related deaths worldwide. Smoking remains the most important risk factor, although non-smokers can also develop lung cancer due to passive smoking, air pollution, occupational exposures, or genetic factors. Early symptoms may include a persistent cough, coughing up blood, chest pain, breathlessness, unexplained weight loss, or repeated chest infections. Unfortunately, lung cancer often causes few symptoms in its early stages, making timely evaluation especially important.

Diagnosis usually involves imaging tests and specialised procedures to confirm the type of cancer. Treatment may include surgery, chemotherapy, radiation therapy, targeted therapy, immunotherapy, or a combination of these approaches. Quitting smoking, avoiding tobacco exposure, and seeking medical advice for persistent respiratory symptoms can significantly improve the chances of early diagnosis and successful treatment.
