What is a Digital Rectal Exam (DRE)?
A digital rectal exam (DRE) is a clinical procedure where a healthcare provider inserts a gloved, lubricated finger into the rectum to check for abnormalities. This exam is often used to evaluate the prostate gland in men and can help detect potential issues such as cancer.
How is a DRE Performed?
During a DRE, the patient may be asked to stand and bend forward at the waist or lie on their side with knees drawn to the chest. The healthcare provider will then gently insert a lubricated, gloved finger into the rectum to feel for any irregularities in the texture, shape, or size of the prostate or lower rectum.

A DRE is generally considered safe. However, it may cause temporary discomfort or minor bleeding, especially if there are pre-existing conditions such as hemorrhoids. It's important to communicate any discomfort to the healthcare provider immediately.
Who Should Get a DRE?
Men over the age of 50 are typically advised to undergo regular DREs as part of their routine health check-ups. Those with a family history of prostate or colorectal cancer, or other risk factors, may need to start screening earlier. Women may also undergo a DRE as part of a pelvic exam to check for abnormalities in the rectum and lower abdomen.
What Happens After the Exam?
If any abnormalities are detected, the healthcare provider may recommend further tests, such as a
PSA test,
colonoscopy, or imaging studies like MRI or CT scans. Biopsies may also be performed to confirm the presence of cancer cells.
How Effective is a DRE in Detecting Cancer?
While a DRE is a valuable tool, it is not foolproof. It's often used in conjunction with other diagnostic tests to provide a more comprehensive evaluation. For example, a DRE can sometimes miss small cancers or those located in areas that are hard to reach with a finger.
What Should You Discuss with Your Doctor?
Before undergoing a DRE, discuss any symptoms you may have, such as changes in bowel habits, pain, or discomfort. Also, inform your healthcare provider of any family history of cancer or other risk factors. This information can help guide the examination and subsequent steps.
Conclusion
A digital rectal exam is a simple, yet effective tool for the early detection of prostate and colorectal cancers. Although it may cause some discomfort, the benefits of early detection far outweigh the temporary unease. Regular screenings, especially for those at higher risk, are essential for maintaining health and catching potential issues early.
