Is it possible to have a positive DRE exam and not have PC?

Hi ~ AEG, I hope this helps!  ~ Lee     Excerpt from: “Dr. Peter Scardino's Prostate Book ” 2006 Peter T. Scardino, M.D. Chairman of the Department of Urology ant Memorial Sloan-Kettering Cancer Center and Judith Kelman Chapter 9 Page 150   The results of a digital rectal exam (DRE) are highly subjective.   The same thing one doctor finds suspicious might be entirely overlooked or deemed insignificant by a different examiner.   Tiny lumps or bulges may represent meaningless calcifications or benign enlargement of the glad.   Only one in five abnormal DRE’s turns out to be cancer. 3   3 Catalona WJ, Richie JP, Ahmann FR, Hudson MA, et al: Comparison of digital rectal examination and serum prostate specific antigen in the early detection of prostate cancer: results of a multicenter clinical trial of 6,630 men. J Urol 1994; 1283-1290.   I found this link …but the percentage shows 1 in 4 http://www.prostatecancer.realage.com/content.aspx/topic/34     Excerpt from “Dr. Patrick Walsh’s Guide to Surviving Prostate Cancer”…(Give Yourself a Second Opinion) 2001 Patrick C. Walsh, M.D. Professor of Urology, The Johns Hopkins Medical Institutions and Janet Farrar Worthington Chapter 5 Page 111 PSA is prostate-specific, not cancer-specific.   This is why a blood test alone isn’t enough, why a digital rectal exam is also a must.   You can have prostate cancer and still have a low PSA level.   And, just because you have a high PSA does not necessarily mean you have prostate cancer—many men with high PSA levels don’t.   about a quarter of men who turn out to have prostate cancer have a low PSA level, less than 4 nanograms per milliliter.   about 25 percent of men with a PSA between 4 and 10 turn out to have cancer.
