I hope you found the info to your queries. The biopsy is a simple procedure and the only way to diagnose cancer. The positive DRE is alarming but it could be due to calcification at the area touched by your doctor.
We all get scared because we do not know about the facts, however, prostate cancer is treatable and at the most it can be controlled for long periods of time. I would recommend you to get a book on diagnosis of Prostate cancer, and that you search the net for a list of questions so that you can understand better when visiting the specialists, just type "Questions+to+Ask+the+Doctor" in a search engine.
I was 50 y/o when diagnosed with PCa back in 2000. I had two failed treatments but my cancer is "under control" with HT manipulations. In your cases, you have not yet been diagnosed with PCa. The difficulty in peeing could be due to hyperplasia which is a benign issue of the prostate.
Should you be positively diagnosed, then you should get second opinions from reliable physicians. You shouldn't decide on anything without knowing the pros and cons.
Do things coordinately and timely.
