For low-risk prostate cancer, watchful waiting is the safe way to go.  In watchful waiting, or active surveillance, instead of treatment with surgery or radiation, a man is closely monitored. That could include a digital rectal exam and prostate-specific antigen blood test every 6 months, and a biopsy if needed.  Many experts recommend watchful waiting when a prostate cancer is small, seems slow-growing, causes no symptoms, and is confined to the prostate.

In a recent Johns Hopkins University study of 1,298 men with low-risk prostate cancer who were carefully monitored, fewer than 1 percent died or saw their cancer spread over 15 years. If your cancer is high-risk or advanced, you’ll probably need treatment right away.
