I may I have covered this topic before but not as it applied to me, personally. I noticed something last night after I took off my bra. There is a two to three inch area on the underside of each of my new breasts that has some keloid scarring. These spots didn’t have tape on them consistently as they are furthest out towards my sides and the tape kept coming off there.
Imagine if skin could simmer like water and then be frozen in that state. That’s what keloid scars look like. Here’s a photo of keloid scars on someone’s chest.
Doctors do not understand exactly why keloids form in certain people or situations and not in others. Changes in the cellular signals that control growth and proliferation could be related to the process of keloid formation, but these changes have not yet been characterized scientifically.
The methods now available to treat keloids are:
- Cortisone injections (intralesional steroids): These are safe and not very painful. Injections are usually given once per month until the maximum benefit is obtained. Injections are safe (very little steroid gets into the bloodstream) and usually help flatten keloids; however, steroid injections can also make the flattened keloid redder by stimulating the formation of more superficial blood vessels. (These can be treated using a laser; see below.) The keloid may look better after treatment than it looked to start with, but even the best results leave a mark that looks and feels quite different from the surrounding skin.
- Surgery: This is risky, because cutting a keloid can trigger the formation of a similar or even larger keloid. Some surgeons achieve success by injecting steroids or applying pressure dressings to the wound site after cutting away the keloid. Radiation after surgical excision has also been used.
- Laser: The pulsed-dye laser can be effective at flattening keloids and making them look less red. Treatment is safe and not very painful, but several treatment sessions may be needed. These may be costly, since such treatments are not generally covered by insurance plans.
- Silicone sheets: This involves wearing a sheet of silicone gel on the affected area for several hours a day for weeks or months, which is hard to sustain. Results are variable. Some doctors claim similar success with compression dressings made from materials other than silicone.
- Cryotherapy: Freezing keloids with liquid nitrogen may flatten them but often darkens the site of treatment.
- Interferon: Interferons are proteins produced by the body’s immune systems that help fight off viruses, bacteria, and other challenges. In recent studies, injections of interferon have shown promise in reducing the size of keloids, though it’s not yet certain whether that effect will be lasting. Current research is underway using a variant of this method, applying topical imiquimod (Aldara), which stimulates the body to produce interferon.
- Fluorouracil: Injections of this chemotherapy agent, alone or together with steroids, have been used as well for treatment of keloids.
- Radiation: Some doctors have reported safe and effective use of radiation to treat keloids.
This is not a very common complication, but it can happen. There doesn’t seem to be a bias. It happens equally in men and women as well as all ethnicities.
