BPH vs Prostate cancer and prostatitis
How to tell BPH and Prostate cancer and prostatitis apart when a board question makes them look alike.
BPH is smooth transition-zone obstruction; cancer is hard peripheral-zone malignancy; prostatitis is painful inflamed prostate.
Side by side
BPH causes lower urinary tract symptoms from periurethral transition-zone nodular hyperplasia with smooth enlarged prostate.
Prostate cancer often arises in peripheral zone as hard nodule; prostatitis causes pelvic pain, dysuria, fever or tender boggy prostate depending on type.
DHT-driven stromal and glandular hyperplasia compresses the urethra without malignant invasion.
Cancer involves malignant glandular proliferation; prostatitis involves inflammatory or infectious prostate disease.
Smooth enlarged prostate, hesitancy, weak stream, nocturia, and transition-zone enlargement support BPH.
Hard irregular nodule, suspicious biopsy, or elevated PSA supports cancer; fever and tender boggy prostate support acute prostatitis.
The trap
Urinary symptoms and PSA can overlap, so exam texture, pain, fever, and biopsy context separate them.
Watch it explained
The repair move
For prostate questions, separate obstructive smooth enlargement from hard malignancy and painful inflammation.
Try a free question
CoreA 68-year-old man has 2 years of progressive urinary frequency, urgency, nocturia (3 times nightly), weak stream, and incomplete emptying. Digital rectal exam reveals a smoothly enlarged, firm, non-tender prostate without nodules. PSA is 4.8 ng/mL. Which diagnosis is most likely?
Show answer and explanation
Answer: A. Benign prostatic hyperplasia. BPH is periurethral transition-zone nodular hyperplasia in older men with progressive obstructive lower urinary tract symptoms and smooth symmetric prostatic enlargement on DRE; treatment is alpha-blockers (tamsulosin) and 5-alpha-reductase inhibitors (finasteride).
Why the other choices are tempting
- B. Prostate adenocarcinoma typically presents with a hard nodule in the peripheral zone on DRE, not smooth enlargement.
- C. Acute bacterial prostatitis presents with fever, dysuria, and an exquisitely tender boggy prostate.
- D. Chronic prostatitis has pelvic pain and dysuria without obstructive urinary symptoms or smooth enlargement.
- E. Bladder neck contracture occurs after prior surgery and shows narrowing on cystoscopy rather than prostatic enlargement.
