I just went thru the same thing and I am 58 yrs old. My PSA was 4.3, free PSA was around 17%. Local Doc did DRE, noted one side was larger but wasn't firm. Did 2 weeks of antibiotic to rule out infection. He scheduled a MRI with and without contrast. I freaked out, all but assumed I had PC and started a thread here. Took many peoples advice and got in at Mayo in Rochester for an initial visit before my MRI. Decided to keep local MRI appointment, as Mayo was further out (like 2 months). Mayo Doc said they would be fine with local MRI and they would read the results and make their own determination as to proceeding with biopsy. I was scheduled with Dr Paris Shah, but was seen by PA Fleenor. She was excellent, put my mind at ease and was very thorough on what the steps would be if there was anything suspicious.
Just got the results from her. No lesions present, lymph nodes normal. Pirads 2 show low, clinically significant cancer is unlikely to be present. She said at this time no biopsy is needed, and to check PSA yearly.
Moral of the story is this, follow the process and don't read too much into these forums, as most people don't ever follow through when they get good results as they usually breath a sigh of relief and move on.
It's good to be pro active, and Jeff Marchi is a wealth of information here. I would listen to his advise.
