Five year survival rate

The five year survival rate is a figure used in medicine for estimating the prognosis of a particular disease.

It is most commonly cited in cancer statistics. In this practice it describes the percentage of patients who are alive at least five years after their cancer is diagnosed. It can also be used to compare the effectiveness of treatments.

Use of 5-year survival statistics is more useful in aggressive diseases that have a shorter life expectancy following diagnosis (such as lung cancer) and less useful in cases with a long life expectancy such as prostate cancer.
