Don’t mean to make you even more anxious but you REALLY should find someone out of your area who does transperineal biopsies.
Not only is the chance for blood infection greatly reduced, but access via the perineum affords greater access to the entire gland and they can get samples from areas very hard to reach with a transrectal approach.
Also, the very cavalier attitude of the nurse (who represents the Doctor!) tells me that these people either don’t care or are inept. OF COURSE you should have a biopsy with those results - are they nuts!!??
Anyway, make an investment in your future - since that’s where you’re at - and see if you can find a center of excellence or large university hospital that’s a few hours away by car or plane if necessary. Best of luck!
