Early stages like IA1 can have up to 92% survival, while stage IVB has almost none. On average, Stage 1–2 patients may live 33–55 months, Stage 3 about 12–28 months, and Stage 4 about 4–9 months. For small cell lung cancer, limited-stage survival is 12–16 months and extensive-stage 7–11 months.
Yes, many people live close to normal lives after lung cancer, especially with early detection and effective treatment. Modern therapies such as surgery, targeted therapy, and immunotherapy have greatly improved both survival rates and quality of life.
Lung cancer cannot be fully prevented, but risk can be reduced significantly. Avoid smoking, quit if you smoke, stay away from secondhand smoke, reduce radon exposure, and limit occupational hazards like asbestos. Healthy diet and exercise help overall health, but no vitamin or supplement is proven to prevent lung cancer.

Breakthroughs include targeted drug combinations like amivantamab with lazertinib, which can extend survival by many months, and immunotherapy combinations such as nivolumab with ipilimumab plus chemotherapy, which improve long-term survival. Other advanced options include drugs like Tagrisso, Imfinzi, and Lorbrena for specific genetic subtypes. Personalized treatment is now the global standard.
