Peyronie's disease: when it curves
Published · Last reviewed · How we review →
A penis that has developed a curve, a bend, or a palpable lump can be alarming — and the internet makes it worse. So, plainly: Peyronie's disease is common, it is not cancer, and it is treatable. It's scar tissue, and the one thing that matters most to your outcome is understanding which phaseyou're in, because that decides what should — and shouldn't — happen next.
What it actually is
Peyronie's is a fibrous plaque— a patch of scar tissue — in the sheath that wraps the erectile chambers. It's thought to follow small injuries during sex that, in men who are predisposed, heal into scar instead of resolving. That predisposition is partly genetic: it overlaps with Dupuytren's contracture (the same kind of fibrous cording in the palm) in roughly a fifth of cases. It is not an infection, not contagious, and not a cancer.
The two phases — and why timing is everything
Peyronie's moves through two phases, and nearly every treatment decision hinges on telling them apart:
Acute · active
Roughly the first year. The plaque is still forming — pain with erections, and a curve that's still changing. The rule here: don't operate on a curve that hasn't settled.
Chronic · stable
The curve has held steady for a few months and the pain has usually gone. Now the deformity is a known quantity — and durable treatment decisions finally make sense.
What can be done
During the active phase, the first move is often to do less: reassurance, letting the plaque stabilize, and resisting the urge to fix a curve that's still moving. Oral pills marketed for Peyronie's have thin evidence behind them.
Once it's stable, real options open up — all of them clinician-delivered:
- Injections into the plaque. An FDA-approved enzyme (collagenase) can reduce curves greater than 30° in men with intact erections; verapamil and interferon are other in-office options.
- Traction therapy.A medical device worn on a schedule under a clinician's guidance, with growing evidence for reducing curvature and recovering some length — often paired with injections.
- Surgery. For a severe curve, or when erectile dysfunction comes with it: procedures that straighten (plication or grafting), or a penile implant when erections no longer respond to other treatment.
Which path fits depends on the size of the curve, how your erections are doing, and your goals — a urologist's call, made once the disease is stable.
When to see someone
A new curve, pain with erections, a lump you can feel, or erections that have become unreliable — those are reasons to see a urologist, not to wait it out in silence. Peyronie's travels with erectile dysfunction often enough that a proper workup should look at both at once, and a real evaluation is where the phase and the plan get sorted.
The bottom line
Peyronie's disease is common, it is not cancer, and it is treatable. The single most important thing to know is that timing rules: let the active phase settle before making any permanent decision, then match a treatment to the curve you're actually left with. Alarming as a new bend is, it runs on a well-worn medical path — and it starts with an exam, not a search bar.

Common questions
Is Peyronie's disease cancer or dangerous?
It is not cancer and not an infection — it is a fibrous scar, or plaque, that causes curvature. It is common and treatable, and the key is matching treatment to the phase.
Can Peyronie's disease be treated without surgery?
Once it is stable, non-surgical options include injections such as collagenase and traction therapy. During the active phase, the priority is usually to let it settle before making permanent decisions.
When should I see a doctor about penis curvature?
A new curve, pain with erections, or a lump you can feel is worth a urologist — especially since Peyronie's often travels with erectile dysfunction.
