The most common side effect of ordinary biopsies is bleeding.
Cancer cells will surely leave the prostate gland getting into the blood stream, but chances for metastasies are considered negligable.
Occasionally infections will occur which is very serious and life-threatening.
I had my ordinary biopsy in 2001, for side effect just bleeding. I am now on AS. No way I will agree to have another such biopsy.
Instead of the ordinary biopsy I had two fine-needle aspiration biopsies, their complication rate being just 0.9%.
Ordinary biopsies have a complication rate of 19.8%.
Ordinary biopsies extract tissue that is examined for cancer, establiishing gleason.
Fine-needle aspiration biopsies scan the whole prostate for cancer cells.
From cancer cells you can get a DNA-Analysis showing cancer yes or no and malignancy.
Unfortunately I had to travel a long way to get this done as urologists are not trained in the technique.
