What is a keloid and why does it come back?
A keloid is a scar that grows beyond the original wound — sometimes painful, itchy or affecting appearance. It has a strong tendency to return when treated with surgery alone. That is why, in many cases, the best result comes from combining surgery with a treatment that controls that growth, such as radiotherapy.
How does radiotherapy help?
Radiotherapy is given shortly after keloid surgery, within hours or days depending on the protocol. It acts on the cells that drive the scar's excessive growth and substantially reduces the risk of recurrence compared with surgery alone. It is delivered with superficial or electron radiotherapy techniques, aimed only at the treated area.
What treatment is like
Treatment is outpatient, quick and painless: each session lasts a few minutes and only a few sessions are needed. Dr. Baquero coordinates the timing with your surgeon to deliver radiotherapy at the right moment, and explains wound care and what to expect from the scar. With external radiotherapy you are not radioactive.

When is radiotherapy done, before or after surgery?
Generally after keloid surgery, within a short window. That is why coordinating in advance between the surgeon and the radiation oncologist is important.
How many sessions are needed?
Usually only a few sessions, brief and painless. The exact number is defined at the assessment based on the keloid's characteristics.
