In evaluating suspected prostate cancer, which physical examination finding is commonly used prior to imaging or biopsy?

• A. Digital rectal exam findings
• B. Urinalysis
• C. Chest X-ray
• D. Renal ultrasound

Answer: (A)

In evaluating suspected prostate cancer, a digital rectal examination is used to palpate the prostate and check for abnormal findings before proceeding to imaging or biopsy. Through the rectal exam, a clinician assesses the prostate’s size, shape, symmetry, and consistency, looking for irregular, hard, nodular, or indurated areas. Such abnormal DRE findings raise concern for malignancy and help guide decisions about imaging or biopsy. Urinalysis, chest X-ray, and renal ultrasound don’t provide the same immediate physical evidence of a prostatic cancer and are not the standard pre-imaging physical exam finding in this context.
