A digital rectal examination (DRE) is a simple procedure doctors use to examine the lower rectum and other internal organs. To perform a DRE, your doctor will gently insert a gloved, lubricated finger into your anus.
It takes less than 2 minutes. It may be used to obtain feces for a fecal occult blood test (used to screen for gastrointestinal bleeding or colon cancer).
It is not as accurate as colonoscopy. But the DRE testing is quick and virtually costs nothing, and may help alleviate your anxiety.
