Prostate cancer is consistently a leading cause of cancer in men, affecting about 1 in 8 men in their lifetime, according to the American Cancer Society. The risks increase as you get older, and most medical professionals recommend screenings between the ages of 40-45 for men who have one or more direct relatives (a father, brother or paternal uncle) who have been diagnosed with prostate cancer.
By age 50, men with an average risk of prostate cancer should start getting screened during annual physicals.
