Before starting TRT my PSA was 0.3 my last blood check showed it was 0.4
I am sure others will chime in and post links to acticles, etc.
The short answer is no. It does not "cause" prostate cancer. It is however a player in cancers that already exist that are affected by androgens.
Do a search of this forum. You find a treasure trove: https://www.excelmale.com/community/search/16303/?q=prostate&c[title_only]=1&o=date
So it seems like your PSA went up, indication that TRT contribute to prostate cancer may be.
A biopsy is the only way to diagnose prostate cancer
