Digital Rectal Examination
Digital rectal examination (DRE) is a procedure where the examiner inserts a gloved, lubricated finger into the rectum to check the size, shape, and texture of the prostate. Areas that are irregular, hard, or lumpy need further evaluation, since they may contain cancer. Although the DRE evaluates only the back of the prostate, 85% of prostate cancers arise in this part of the prostate. Prostate cancer that can be felt on DRE is, in general, more advanced. The use of DRE has never been shown to prevent prostate cancer deaths when used as the only screening test.

Famous quotes containing the word examination:
“Maybe it’s understandable what a history of failures America’s foreign policy has been. We are, after all, a country full of people who came to America to get away from foreigners. Any prolonged examination of the U.S. government reveals foreign policy to be America’s miniature schnauzer—a noisy but small and useless part of the national household.”
—P.J. (Patrick Jake)
