You have received some great post with information. MCC is a great source for information and personal dealings with a disease that hopefully one day can be prevented all together.

I wanted to pass on to you that looking at the 4.0 number (standard is that below that is normal PSA) is not what my PCP or R/O or Urologist at Mayo Clinic used to decide to do a MRI, biopsie, and many diagnostic tests. It was the continued rising of the PSA over years. I think you stated once a year you get them. I have been having a 3 month PSA test done for years prior to getting additional test done. My PCP started doing that (testing) every 3 months a couple of years prior diagnostic testing because of rising PSA numbers.

I don't think you need to worry about past CT affecting or giving you prostrate cancer. PC is a very common cancer among men with almost every urologist saying if you live long enough you will get it. Most of the time it is the type Andi that is slow growing and an unique form of cancer with abnormal cells that a lot of R/Os and urologist say subjective diagnosis thus the second opinions on any biopsies.

Many things can cause your PSA to go up. It is important to look at PSA over time and over many tests. Is it one spike and return, one spike and stays the same, or a spike and continuing to rise. It is the spike and continuing to rise that my Mayo doctors did not like. I NEVER got above 4.0 but my PCP decided to refer me to urologist who concurred and ordered diagnostic tests and it was prostrate cancer but caught very early.

I know you will be getting a lot of suggestions and feedback (which is why MCC is here) but insist you have a urologist who is experienced with prostrate cancer. Also consider second opinions. I did and they came back the same diagnosis and same treatment recommendations.

I think I am reading right that you had the only 1 high bump over the years. Have you had a follow up PSA since the little over 4.0? IF not I would be asking now for every 3 month PSA test and then see the trend to single spike, or spike and continuing to rise over time.
