Can Frequent Bowel Movement And PSA Of 3 Symptoms For Prostrate Cancer?

HI.....Thanks for your help. I have been monitoring my PSA levels for many years. I am 56 years old and my PSA levels have fluctuated up and down from 2.6 to 3.3 over time. In 2008 it was 3.1 and just 2 wks ago it was 3.0. I had a Colonoscopy on on the 28th of November and was concerned about my PSA, so I asked my DR. to do another PSA. In 11 days PSA went from 3.0 to 3.4. He said it was most likely due to the trauma of the colonoscopy. On Nov 19th I had a PSA of 3.00, up from 2.7 last year and 2.8 on Dec 2010, so you can see how it moves up and down. I have to take pain medication (Loratab) daily for over a year and was told that constipation can cause elevated PSA readings. I am now taking more natural fiber, ie Metamucil, but will frequent Bowel Movements make PSA levels go up also. I am now concerned that frequent bowl movements may be as harmful in raising PSA levels as constipation. I have no Family history of Prostate cancer, but have had 2 friends diagnosd with it within the past 2 years. Should I be concerned?

Both my Dr's say no
