Digital Rectal Examination (DRE)

Why It Is Done

A digital rectal exam (DRE) is done to:

• Check for growths in or enlargement of the prostate gland in men. A tumor in the prostate can often be felt as a hard lump. This may be done as part of a regular examination or to check on symptoms, such as a change in urination. Not all problems of the prostate can be felt through the rectum.
• Check for problems in a woman's reproductive organs, such as the uterus and ovaries. It is often done during a regular pelvic examination and Pap test. It may also be done to check on symptoms, such as pelvic pain or vaginal bleeding.
• Help find the cause of symptoms such as rectal bleeding (blood in the stool), belly or pelvic pain, a change in urination, or a change in bowel habits.
• Collect a stool sample to test for blood in the stool.
• Check for hemorrhoids or growths, such as cancer, in the rectum. DRE alone is not used to diagnose colorectal cancer. Also, a DRE may not find internal hemorrhoids because they are soft and hard to feel; a sigmoidoscopy may be needed to diagnose internal hemorrhoids.
