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

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.
