The digital rectal exam (DRE) is a screening tool for the early detection of colon/rectal (colorectal) cancer and prostate cancer. This test is often called a rectal exam or prostate exam. The American Cancer Society recommends that everyone over the age of 40 have an annual digital rectal exam.

How do I prepare for this test?

No special preparation is necessary for the examination. You will be asked to change into a patient gown.

How is this test performed?

Noordwijk hotel roomsDuring this examination, a doctor inserts a gloved, lubricated finger into the patient's rectum and examines the smoothness of the rectal wall surface for lesions, or for an abnormally firm area that might indicate cancer. In men, the doctor will also examine the size and characteristics of the prostate. The prostate gland is located next to the rectum, and most cancers begin in the part of the gland that can be reached by a rectal exam. During this exam, the doctor may also obtain a stool sample for a fecal occult blood test that checks for the presence of blood.

How long does the procedure take?

A DRE takes from 5 to 10 minutes.

What happens if an abnormality is found?

Since the DRE is a screening tool, if an abnormality is detected, additional testing may be ordered. If a suspicious lump or area is detected, and the doctor suspects a prostate problem, you may be advised to have a protein-specific antigen (PSA) blood test, transrectal ultrasound (TRUS), or a biopsy of the prostate. If a rectal/colon problem is suspected, a colon examination may be recommended.

About half of the time, a suspicious lump in the prostate, rectum, or colon does not turn out to be cancer.

Are there any risks associated with this test?

There are no risks associated with the exam.

What is a desirable result?

The rectum should feel smooth without abnormalities or unusual lumps, swelling, or tenderness. For men, the prostate should be symmetrical, about the size of a walnut, and absent of any nodules or polyps.
