If you do not want to read about survival rates for small cell lung cancer, stop reading here and skip to the next section. The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed.Of course, many of these people live longer than 5 years.To get 5-year survival rates, doctors look at people who were treated at least 5 years ago. Improvements in treatment since then may result in a more favorable outlook for people now being diagnosed with small cell lung cancer (SCLC).f course, many of these people live longer than 5 years.
