The five year relative survival rate is an estimate of the proportion of patients who would be expected to survive the effects of their cancer at least five years after their initial cancer diagnosis if the only possible cause of death for the patient was the cancer they were diagnosed with.

The Surveillance, Epidemiology, and End Results (SEER) Program provides information on cancer statistics in an effort to reduce the cancer burden among the U.S. population. SEER is supported by the Surveillance Research Program (SRP) in NCI's Division of Cancer Control and Population Sciences (DCCPS).

All incidence and mortality rates in these reports are age-adjusted to the 2000 US standard population.
