There is no way any of us here - or your doctor for that matter - can really answer your question about your "odds" for PCa, other than just quoting broad statistics. And those odds would predict that you do NOT have it!
Having said, that I still think your choice to have a biopsy is a good one. Please ask ahead of time if yours will be done under anesthesia or not...that makes a real difference in your comfort during the procedure...not so much re after affects (which are generally mild).
I'm sure all of us worried between the time we made the biopsy decision and the time it was done, so I would be less than candid to advise you not to worry. However, as other have posted, even if you get bad news the cancer is generally slow growing and you shouldn't worry about harm from the dealy. And, if the news is bad, you probably caught it very early so you have lots of treatment options.
I'm hoping you get good news, however, so please come back and let us know. And, try to enjoy the holidays!
