Lung cancer progresses through stages I–IV based on tumour size and spread. Early stages may cause a persistent cough, chest pain, shortness of breath or coughing up blood, while later stages often include weight loss and fatigue. Early detection greatly improves survival: stage I has 5-year survival up to ~70-90%, stage II ~50-60%, stage III ~20-40% and stage IV drops to ~3-7%.
With guidance from Surgical Oncology Solutions, understanding symptoms, stage-based treatments like surgery, chemo and targeted therapy and realistic survival rates helps patients make informed care decisions for better outcomes
