Went back for a folliw up psa was 1.2.. several months later had some prostatitis symptoms again went to doc psa was .09 urine sample had small trace of blood.. she sent me to a uroligist about 1 month to get appointment.. no more prostatitis symptoms but gave another urine sample small trace of blood..

Ello, Thanks for choosing Chat Doctor for posting your query. I have gone through your question in detail and I can understand what you are going through. Prostatitis is difficult to treat illness and sometimes the infection just stays back to appear later on. You may have to do culture and sensitivity of the semen to identify the causative organism. Yes there is a possibility of cancer as well but as the PSA is mostly coming back normal, it is likely that there may not be any cancer. But still your decision is good to get a CT scan of the abdomen done. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you. In future if you wish to contact me directly, or want to further details about your query, you can use the below-mentioned link:bit.ly/ Chat Doctor.
