net survival


Net survival represents the probability of surviving cancer in the absence of other causes of death. It is used to give an estimate of the percentage of people who will survive their cancer.

For example, a type of cancer may have a 5-year net survival rate of 67%. This means that, on average, about 67% of people diagnosed with that type of cancer will survive for at least 5 years (adjusted for other causes of death).

Net survival has become the preferred way of analyzing survival for people with cancer. Five-year net survival rates are commonly used.
