What are the stages, symptoms, and standard treatments for lung cancer?
Lung cancer is usually classified into stages 1 to 4, depending on tumour size and spread. Early stages may have few symptoms, while common signs include a persistent cough, chest pain, shortness of breath, coughing up blood, fatigue, or unexplained weight loss. Treatment depends on the stage and type of cancer and can include surgery, chemotherapy, radiotherapy, targeted therapy, or immunotherapy, often combined for best results. Supportive care is also important to manage symptoms and improve quality of life. Early detection and following your doctor's treatment plan give the best chances for control or recovery.
