How long an individual will live after a diagnosis of cancer (prognosis) is affected by a range of factors, such as the specific characteristics of the individual, including their age and general health at the time of diagnosis, the type and stage of cancer they have and the treatments received.
Please note, 5-year relative survival does not reflect an individual's chance of surviving cancer.
5-year relative survival estimates are derived by comparing the survival of people diagnosed with cancer (observed survival) with that expected by people in the general population of equivalent age, sex and calendar year (expected survival).
The ratio of observed to expected survival is used as an indicator of the proportion of people who survived their cancer.
The 5-year relative survival for bowel cancer increased from 48% to 69.9% between 1982-1987 and 2011-2015.
For example, 5-year relative survival of 69.9% for people diagnosed with bowel cancer means these people had a seven in ten chance of surviving five years after diagnosis relative to comparable people in the general population.
