You'll probably get lots of replies, but since I'm 6 weeks post-op, here's my 2 cents worth...

Not alone at all. You've absolutely come to the right place.
I remember every step of this & the biopsy wasn't too bad. No pain- just uncomfortable. You'll be alright.
The worst part was waiting for the results.

PSA blood tests & MRI scans (if you had one) can only be a cause for "concern". They don't really know what's going on until they can get actual samples from the prostate. That's the biopsy.
You'll meet with the urologist for the results (I had to wait a very stressful 6 weeks).
But it'll probably be quicker in your country.

If cancer is diagnosed, you'll be asked to consider a number of options.
One is to wait & have regular tests to see if things change.
Another is to have radiation treatment.
Another is to have surgery to remove the prostate.
You don't have to decide then & there.

But there are lots of knowledgeable guys here who have been through this, so come back here with any & all concerns while you wait for the results and after the results come through.
Good luck.
