Depending on the part of the body treated, EBRT may make skin in the treatment area dry, itchy and flaky. Your skin may change in colour (look red, sunburnt or tanned) and may feel painful. Skin changes often start 10–14 days after the first treatment. They often get worse during treatment, before improving in the weeks after treatment.
You may need dressings and creams to help the area heal, avoid infection and make you more comfortable. Pain medicine can help if the skin is very sore. Let your radiation therapy team know about skin changes, such as cracks or blisters, moist areas, rashes, infections, swelling or peeling.
Taking care of your skin
- Clean skin with warm water and a mild unscented soap. Gently pat skin dry with a soft towel.
- Ask your doctor or nurse what type of water‑based moisturiser to use. Avoid perfumed or scented products.
- Start moisturising from the first day of treatment. Apply moisturiser at least 2 hours before or after each session.
- Protect your skin outdoors. The sun can irritate skin changes and delay healing.
- Let temporary skin markings wear off by themselves. Don’t scrub your skin to remove them.
- Avoid using razors, hair dryers, hot water bottles, heat packs, wheat bags or icepacks on the area that has been treated.
- Wear loose, soft cotton clothing. Avoid tight‑fitting items in the treatment area.
- Check with your doctor about swimming. Chlorine may worsen skin reactions for some people.
