How long is a prostate biopsy needle?
Biopsy needles are tiny — only 1.2 millimeters in diameter and less than 1/2″ long — and very precise. A sliding sheath opens once the needle enters the prostate, closes onto a sample of tissue and the needle is withdrawn. A sextant (six-part) biopsy is the most common prostate biopsy procedure.
