During digital rectal examination, which finding would raise suspicion for cancer rather than benign prostatic hyperplasia?

• A. Prostate hard, nodular, irregular.
• B. Prostate large but smooth.
• C. Prostate small and nonpalpable.
• D. Prostate enlarged with soft consistency.

Answer: (A)

During a digital rectal examination, the feel of the prostate is used to distinguish benign enlargement from malignancy. Cancer often presents as a hard, nodular, and irregular area within the gland, sometimes eccentric or asymmetric and may feel fixed to surrounding tissues. This abnormal texture and contour reflect malignant tissue disrupting the normal smooth architecture.

In contrast, benign prostatic hyperplasia usually causes a symmetrical enlargement that feels smooth and more rubbery or stony, without hard nodules. A prostate that is large but smooth fits this benign pattern, not cancer. A small and nonpalpable prostate isn’t the classic cancer sign on DRE; it isn’t the typical clue pointing toward malignancy. An enlarged prostate with soft consistency points away from cancer and toward benign processes like BPH or prostatitis, which tend to feel less firm.

So the hard, nodular, irregular prostate is the finding that raises suspicion for cancer rather than benign enlargement.
