We've all been there, Pete. Waiting for results is the hardest part of the whole process. You should be aware of the fact that roughly 70% of men your age DO have prostate cancer, so the odds are that the biopsy results will come back positive. Don't get too stressed about it. You get diagnosed, if necessary you get treated, and then you get on with your life. Localised prostate cancer is a very treatable condition. I got diagnosed in 2018, treated in 2019, and I'm enjoying life. A diagnosis of localised prostate cancer is certainly a game-changer, but it's not a death sentence.
Just take it a day at a time. You'll know where you stand in the next few weeks, and most people feel a lot better about it then.
All the best,
Chris
