Lung cancer stage 4 + how long to live?

Lung cancer: Unfortunately, stage 4 lung cancer is almost always fatal. The average survival of people with stage 4 lung cancer who undergo chemotherapy is about a year. Some people live much longer than a year, but only rarely will someone live more than 3-5 years. Discuss your particular situation with your oncologist.

Sadly, not long: The prognosis with advanced lung cancers is not good some therapy may palliative the symptoms, but we have no cure yet. I am very sorry.
