A keloid scar is a benign, overgrown lump that can sometimes develop when a wound heals, or even after minor skin damage such as acne or ear piercing. They may be red or darker in colour than usual skin tone, appearing most commonly on the chest, shoulders, and ear lobes. They are often cosmetically disfiguring but can also cause itching and pain.^1,2

Radiation therapy may be suitable if you have keloid scars.4Radiation therapy reduces the inflammation which in turn dampens the over productivity of the collagen.

Radiation therapy is often used after surgery, with some studies supporting radiation therapy within 24-72 hours post-surgery, to prevent the scar from recurring with studies showing ~85% success rate with no regrowth of the scar.^3,4

A technique called electron beam radiation therapy is used for keloid scars. Delivered by a machine called a linear accelerator (LINAC), it’s very similar to a regular X-ray. This is quite a large machine with an applicator attached to the end, which is positioned close to the treatment area without making contact.

Radiation treatments can be delivered in up to 5 sessions, with each session taking around 15 minutes. There may be some mild redness of the skin immediately following treatment, but this usually disappears over 2-3 weeks.
