No, you won’t have an open wound in the way you do after surgery. IG-SRT does not cut the skin, so there isn’t a surgical incision that needs bandaging. The skin remains intact throughout treatment, though it goes through surface changes (redness, peeling, crusting). You might get something like a moist desquamation toward the end – which is where the top layer of skin peels off and the skin underneath is raw and oozing a bit (like a scraped knee). This is the closest to an “open wound” you’d see, and it can happen in a small area if the reaction is strong. Even then, it’s more like a shallow sore, not a deep wound. That kind of reaction would be managed with ointments and possibly a light dressing, and it usually heals over a few weeks leaving fresh skin beneath.
But in general, most patients do not experience a true open lesion. And importantly, once treatment is done, the skin heals without a scar, since we haven’t excised tissue. There is no need for bandages after you finish treatment unless you have a spot that’s still raw – in which case, a simple bandage can be used until it epithelializes (covers over with new skin).
This means you won’t have to do the kind of wound care that post-surgical patients do (like changing dressings, etc.). You’ll just keep the area clean and moist as described. If at any time a portion does ulcerate (a small portion of patients get a radiation ulcer that takes time to heal), we might dress that like a chronic wound until it closes. But that’s the exception, not the rule, especially with image-guided treatment which tends to avoid excess dosing.
To put it simply: IG-SRT heals by regeneration under an intact skin surface. Dead cancer cells get replaced by new healthy cells growing in, and the top might flake off, but it’s a controlled process with no large defect.
So, you will not be walking around with a big wound or needing bulky bandages. You might choose to cover it with a band-aid for cosmetic reasons or to catch ointment, but medically, no surgical wound care is necessary. This is a relief to many patients who dread wound care or have trouble with wounds in certain areas.
By about a month or two after treatment, any superficial crusts will have resolved and you’ll just have new skin that may be pink. No bandage needed – just sunscreen and normal skincare by that point.
