Small Cell Lung Cancer - The overall 5-year survival rate for both stages of small cell lung cancer (limited stage plus extensive stage) is only about 6 percent. Without treatment, the average life expectancy for extensive disease is 2 to 4 months, and with treatment is 6 to 12 months.
As noted above, when surgery is done at any early stage, has not spread to lymph nodes or blood vessels, doctors may sometimes use the word cure. Surgery may be performed for those with stage 1, stage 2 and stage 3A non-small cell lung cancer.Jan 3, 2018
