“No More Unnecessary Biopsies . . . ” The first four words of the sub-title of our book, Invasion of the Prostate Snatchers,” are a clear statement of our objective. I am no fan of biopsies. At the same time I know that a biopsy is an essential diagnostic tool when appropriately used. The problem is that too many doctors schedule an immediate biopsy if there is only a slight rise in PSA, when it would be more appropriate to explore less invasive diagnostic methods first.
