Non-small cell lung cancer survival rates by stage

Survival rates are often used by doctors as a standard way of discussing a person's prognosis (outlook). Some patients may want to know the survival statistics for people in similar situations, while others may not find the numbers helpful, or may even not want to know them. Whether or not you want to read about the survival statistics below for non-small cell lung cancer is up to you. If you decide that you don’t want to know them, 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 much 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 non-small cell lung cancer.

Survival rates are often based on previous outcomes of large numbers of people who had the disease, but they cannot predict what will happen to any particular person. Knowing the type and the stage of a person's cancer is important in estimating their outlook. But many other factors may also affect a person's outlook, such as the genetic changes in the cancer cells, how well the cancer responds to treatment, and a person's overall health. Even when taking these other factors into account, survival rates are at best rough estimates. Your doctor can tell you how the numbers below may apply to you.

The numbers below are survival rates calculated from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database, based on people who were diagnosed with non-small cell lung cancer between 1998 and 2000.
