A keloid from a prior surgery does not mean every future surgery will keloid. A lot depends on where the scar was. C-sections, shoulders, the central chest, the back, and knees scar thick more often, while breast surgery scars tend to behave better. Having a bad scar in one high-risk area does not doom you to abnormal scars everywhere.
Here's a really common and understandable worry: "I got a keloid scar from a prior surgery. Does that mean every future surgery is going to result in keloids too?"
The reassuring answer: usually not. Let me explain why, because where the scar happened matters a lot, and there's plenty we can do to keep it from repeating.
Here's the key insight most people don't realize: certain areas of the body have much higher rates of keloids and hypertrophic scars (those thick, red, firm scars) than others. So a bad scar in a high-risk zone doesn't necessarily predict how you'll heal elsewhere.
The areas that tend to scar thick:
And notably, thickened scars are less common with breast surgery. So if your keloid came from, say, a C-section or a scar on your chest or back, that does not mean you're doomed to abnormal scars everywhere else on your body. The location did a lot of the work.
Having an abnormal or thickened scar in one of those high-risk areas doesn't mean you're destined for bad scars everywhere.
Preventing bad scars starts on the operating table. Surgeons use all kinds of techniques to minimize this type of scarring, and we do that for every single patient. But if you have a history of poor scarring, we get especially careful, paying extra attention to how the wound is closed and how tension is managed.
Reducing tension on the wound is one of the biggest levers, because tension is a major driver of thick scars.
The other half is what happens after surgery. For patients with a propensity for bad scars, I follow up more aggressively. The goal is simple: I want to catch it early and intervene quickly if the scar starts to misbehave, so we can head off a repeat of what you've already been through.
Scars that are going to turn hypertrophic or keloid usually give you a window early on where treatment works best, so staying ahead of it is everything.
If you know you have a history of bad scars, here are things to bring up with your surgeon:
Talk to your doctor about a Prevena vac (a negative pressure incision device). These are fantastic for a few reasons:
If you want the details on how these devices work, I've broken that down here.
Ask your surgeon about aggressive scar management after surgery. That usually means:
Starting early is the theme, because with scars, prevention and prompt treatment beat trying to fix a thick, mature scar later. If a scar does thicken despite everything, there are still injectable treatments like Kenalog and 5-FU that help.
A keloid from a prior surgery does not mean every future surgery will keloid. A lot depends on where the scar was, some areas (C-sections, shoulders, central chest, back, knees) simply scar thick more often, while breast surgery scars tend to behave better.
If you're a "bad scarrer," the plan is straightforward: surgeons take extra care in the OR to reduce tension, follow up more aggressively afterward to catch problems early, and you can help by asking about a Prevena vac and starting silicone strips, gel, and even early lasers right away. Between location and a proactive plan, one bad scar in the past is not a life sentence for every scar to come.
