Commonly, prostate cancer is slow moving and something else is likely to get you first. There are, however, more aggressive strains.
If there is a sufficient amount, the biopsy samples can be sent out for genetic testing, which will give insight as to the nature of this particular cancer. Typically, the required amount is a biopsy that contains at least 5% cancer, or a minimum continuous length of 0.5 mm. Your urologist will know all about this. I think this is critical information.
I also suggest reading "Invasion Of The Prostate Snatchers", co-authored by Mark Scholz, MD, and his patient Ralph Blum. The local prostate cancer support group highly recommends this book.
Good luck to both of you.
