My father was 1 of 5 boys. One died @ age 40 (alcohol), 3 died of prostate cancer in their late 60's early 70's, the fifth is now 80 but has had prostate cancer but caught it early. I once heard a doctor on TV say that all men over the age of 80 have prostrate cancer in some form or another. It is important that all men over 50 get checked annually. Ken Carpenter
