Could a benign adenomatous polyp cause a high PSA? In 2009 my PSA WAS 3.6. In 2011 it was 7. In dec 2013 - 10.3 and June 2014 - 11.0. I had a prostate biopsy in Dec 2013 and it was negative. I just had a colonoscopy and had 4 polyps removed. They were benign. Any ideas if that could cause a high PSA level
