Why do you think that sharing this story helps anyone in anyway? This answers NO QUESTIONS. It is ONE PERSON'S STORY. Posting this will most likely cause the OP and other readers ANXIETY.
The PSA is within the range for you at present Tel. PSA can rise from an enlarging prostate, infections and other things. If you are concerned, discuss with the doctor and maybe have another PSA test. A recent UTI can also cause a rise. The fact you have had bph diagnosed could be a reason for the rise in PSA levels. Please also be aware that anxiety can increase PSA levels.
For my story, I am 47. I had a PSA test in January that came back at 3.2. I had a DRE that was smooth. I then had another PSA test that came back to 2.2. If it can drop 31% in a few weeks, it can also rise that amount is my logic.
However, since this I have been on heightened alert. As well as changing my diet, walking more and losing 10lbs so far - every back ache gets me thinking that "I have cancer that has spread to the bones".
There are no typical cases, is what I am concluding. There are people with "normal" PSAs that have cancer, there are people with raised PSAs that do not. The PSA is not a test for cancer.
If you really want my advice - I would try to get another PSA in a few months. I'd also consider not asking questions on here. There are people here who offer good advice, but considerably more who speculate, guess, and provide answers based on no scientific basis.
I, myself, have been told that PCa will affect me in 10 years time by one person on this forum, and yet another has told me to stop drinking milk. I know both mean well, but their words did, and still continue to, cause me anxiety. If you have a car issue, you speak to a mechanic. If your toilet is blocked you get a plumber. If you have a rising PSA, talk to the doctor. Not to people like Ashu who, although probably meaning well, has cherry picked some stories. It makes me really really angry.
