Annual checkup saved my life.
Most men with prostate cancer die of something else. Unless you have a family history of lethal prostate cancer or a pathology report that the biopsy had aggressive features, most urologists will recommend what's called watchful waiting.
After my diagnosis I got three opinions from 3 separate physicians; one Family Practice, one Urologist, and one Oncologist. None suggested watchful waiting. Opted for using proton radiation, 44 sessions, killed the tumor, everything now normal.
