We're so sorry for the reason you're here, but you came to the right place! A warm welcome to you!
This is a great place to ask questions and to get support.
Your numbers indicate to me very good reasons to get a biopsy with your PSA rising. My PSA was 4.3 and I caught PCa early.
Look at it this way. If your results come out negative, you've gone through a little discomfort.
** but, remember the prostate biopsy is never a test done "for nothing" **
You and I really need to know if we have cancer or not. There are many on this forum who wish they had caught the disease earlier. If you do find that you have cancer, then you can take charge and find a way to get rid of it.
No one can force you to do anything, but those on this forum will support you in any decision you make to help ensure or re-gain your good health.
