Welcome to our corner of the world, sorry you need to be here but it's a good place to ask questions.
Yes, go see the Uro as that is a high number. Before a biopsy I suggest a retest just to verify the result - there is a possibility of problems with a PSA test. There are a number of things that can raise your PSA and not be cancer. PSA simply indicates that something is up - infection, BPH, sex, bicycle riding, a bad day at the lab, etc.
Your Uro will do a DRE (digital rectal exam) and get your history. There are other blood tests and/or imaging that might be recommended, maybe. Then it's very likely at that a biopsy might be recommended. Or to rule out infection they might give you some antibiotics and then retest.
The only thing I can say for sure is that you're in store for a few doctor appointments and another blood test or two.
Hang in there - I know it can be difficult to deal with the news but even if the worst proves true, there is a lot that can be done. Let us know how it goes with the Uro. and ask any other questions you have.
All the best,
I'll be in the shop.
