A digital rectal exam is a hands-on medical procedure where a doctor inserts a lubricated, gloved finger into the rectum to feel for abnormalities in the lower digestive tract or nearby organs. It's valued for its simplicity and effectiveness in detecting issues like prostate enlargement or early-stage cancers, often serving as a quick, non-invasive first step in diagnostics that complements more advanced imaging techniques in today's healthcare.
