If the cancer is found before it has spread outside the prostate, the five-year relative survival rate is 100 percent.

After Treatment

The five-year survival rates refer to the percent of patients who live at least five years after their cancer is found. Many of these patients live much longer than five years. Eighty-nine percent of men with prostate cancer live at least five years, and 63 percent survive at least 10 years. If the cancer is found before it has spread outside the prostate, the five-year relative survival rate is 100 percent. If the cancer has spread to tissues near the prostate, the survival rate is 94 percent. And if the cancer has spread to distant parts of the body when it is found, about 31 percent will live at least five years.
