1) The lung cancer survival rate depends on several factors like the stage of cancer, age, sex, and ability to tolerate treatment. Stage 1 lung cancer has a 5-year survival rate of 60-80% while stage 4 is below 5%. 2) Younger patients, women, and those who quit smoking have better survival outcomes. Early detection also increases survival rates up to 90% for stage 1 lung cancer. 3) For stage 4 lung cancer, which 40% of patients are diagnosed with, the 5-year survival rate is very low at only 5-10% and average life expectancy is 8 months to 1 year.
