Never mind the PSA, being 67 is the biggest clue that you may have prostate cancer. Once you get above 50 year old your percent probability of having prostate cancer goes up roughly inline with age, so you have a 67% chance of having prostate cancer.
Now when you think about it that must mean an awful lot of your contemporaries have it, but they aren't dropping like flies all around you, and that is because for 80% of men with this cancer they will never even know they have it, they will live to a ripe old age and die of something else.
So the real question is have you got prostate cancer which is aggressive enough that it warrants treatment? That PSA is above normal, but it isn't very high, and the speed it has risen is not necessarily cancer related.
You now need to complete the diagnostic process, and then see what the doctors advise. Hopefully they will suggest Active Surveillance is enough, and you can live another 20 years, fully continent and having erections whenever you want.
You will find plenty of posts on here from men who were not well served by Active Surveillance, it progressed more rapidly than expected, and they needed treatment which may have been too late.
You will not find many posts on this forum about Active Surveillance being successful. That is because the thousands of men who are on it are, down the pub drinking as much as they want, and f****ing as much as they want, and see no need to post on a forum for people suffering from cancer or the side effects of it's treatment.
(This post is in no way meant to detract from those on the forum whose AS failed. It is to try and help the OP see that this forum does not reflect a statistical sample)
