You have a direct genetic history of prostate cancer, thus you are at higher risk than most men. At age 57 I had no family history and no symptoms, yet my primary care doc suggested I be tested anyway. My PSA was in fact elevated. I got a biopsy and found my prostate was 80% cancerous. I got it surgically removed just in time. 10 years later I'm still cancer free.
Every day I five thanks that my doctor did NOT follow the standard medical advice back then NOT to test. Forewarned is forearmed.
