Prostate cancer

Prostate cancer caught early or in nearby tissue both round to 100% five-year survival. Once it reaches distant organs, that figure falls to 40.1%.

Five-year relative survival by stage

Stage at diagnosis 5-year survival Share of cases
Caught early : Still only where it started. This is what screening looks for. 100.0% 69.0%
Spread nearby : Reached lymph nodes or tissue next to where it started. 100.0% 14.0%
Caught late : Reached organs elsewhere in the body. Doctors call this metastatic. 40.1% 9.0%
Stage unknown : The record did not say how far it had spread. 94.1% 8.0%
All cases : Everyone diagnosed, early and late together. 98.2% n/a

Figures are 5-year relative survival by SEER stage at diagnosis from the NCI Surveillance, Epidemiology, and End Results (SEER) program. They describe outcomes by the stage at which a cancer was found; they are not outcomes attributable to whole-body MRI screening, which has not been shown in randomized trials to reduce cancer mortality. What these numbers do and do not show.

Better odds of being alive five years later when prostate cancer is caught before it spreads, compared with after it has reached other organs.

Where cases are caught today

9.0% of prostate cancer cases have already spread to other organs by the time anyone looks.
