BPH vs Prostate Cancer
Both enlarge the prostate, but they sit in different zones and feel different on exam. The classic discriminator: BPH is smooth and rubbery, while cancer is a hard, irregular nodule.

Side by Side
| Feature | BPH (benign) | Prostate cancer |
|---|---|---|
| Nature | Benign (non-cancerous) enlargement | Malignant adenocarcinoma |
| Zone of gland | Central/transitional zone (around urethra) | Peripheral zone (palpable on DRE) |
| Urinary symptoms | Common and prominent (hesitancy, weak stream, nocturia, retention) | Often none early; urinary symptoms appear later |
| Digital rectal exam | Smooth, rubbery, symmetrically enlarged | Hard, irregular nodule or asymmetry |
| PSA | May be mildly elevated | Often higher / rising; confirm with biopsy + Gleason |
| Course | Slowly progressive, not metastatic | Usually slow-growing; can metastasize to BONE |
| Treatment | Watchful waiting, alpha-blockers, 5-alpha-reductase inhibitors, TURP | Active surveillance, prostatectomy, radiation, androgen deprivation |
Exam Traps
- ✦DRE: BPH = smooth, rubbery, symmetric; cancer = hard, irregular nodule.
- ✦BPH arises in the central/transitional zone (causes obstruction early); cancer arises in the peripheral zone (palpable, often silent early).
- ✦PSA rises with BOTH — so an elevated PSA isn't automatically cancer; biopsy + Gleason confirms.
- ✦Prostate cancer metastasizes to BONE — new bone/back pain is a red flag.
- ✦Both are common in older men and can coexist.
