This is my situation. 65 years old, I had a friend who died of prostate cancer so got myself checked out. PSA was slightly high, prostate enlarged, so they monitored me for 5 years before increasing PSA levels triggered a scan and then a biopsy. Cancer was found but small and non-aggressive. I was given the option to have it treated but it was recommended to just leave it alone and keep an eye on it, which is what I'm doing. I just didn't fancy the side effects of treatment
So we'll just see what happens
