Good question and answer. The typical biopsy procedure is often is limited to 12 samples. While some MD's do more, it is possible to have prostate cancer and end of with a report showing 12 non-cancerous samples. Sadly we do not yet live in a perfect world where 100% testing accuracy is reality. Dennis(ProstateCancer.net TEAM)
