When you have radiation treatment for cancer, your body goes through changes.
Two weeks after radiation treatment starts, you might notice changes in your skin. Most of these symptoms go away after your treatments have stopped.
- Your skin and mouth may turn red.
- Your skin might start to peel or get dark.
- Your skin may itch.
Your hair will begin to fall out about 2 weeks after radiation treatment starts. It may not grow back.
Hair and Skin Care
When you have radiation treatment, color markings are drawn on your skin. DO NOT remove them. These show where to aim the radiation. If they come off, DO NOT redraw them. Tell your doctor instead.
To care for your hair:
- For the first 2 weeks of treatment, wash your hair once a week with a gentle shampoo, such as a baby shampoo.
- After 2 weeks, use only warm water on your hair and scalp, without shampoo.
- Dry gently with a towel.
- DO NOT use a hair dryer.
If you wear a wig or toupee:
- Be sure the lining does not bother your scalp.
- Wear it only a few hours a day, during the time you are getting radiation treatments and right after treatment has ended.
- Ask your doctor when you can start to wear it more.
To care for your skin in the treatment area:
- Wash the treatment area gently with lukewarm water only. DO NOT scrub your skin.
- DO NOT use soaps.
- Pat dry instead of rubbing dry.
- DO NOT use lotions, ointments, makeup, perfumed powders, or other perfumed products on this area. Ask your health care provider what is OK to use.
- Keep the area being treated out of direct sunlight. Wear a hat or scarf. Ask your provider if you should use sunscreen.
- DO NOT scratch or rub your skin.
- Ask your doctor for medicine if your scalp gets very dry and flaky, or if it gets red or tanned.
- Tell your provider if you have any breaks or openings in your skin.
- DO NOT put heating pads or ice bags on the treatment area.
Keep the treatment area in the open air as much as possible. But stay away from very hot or cold temperatures.
DO NOT swim during treatment. Ask your provider when you can start swimming after treatment.
You need to eat enough protein and calories to keep your weight and strength up. Ask your provider about liquid food supplements that may help you get enough calories.
Avoid sugary snacks and drinks that may cause tooth decay.
You will likely feel tired after a few days. If so:
- DO NOT try to do too much. You probably will not be able to do everything you are used to.
- Get more sleep at night. Rest during the day when you can.
- Take a few weeks off work, or work less.
You may be taking a medicine called dexamethasone (Decadron) while you are getting radiation to the brain.
- It may make you hungrier, cause leg swelling or cramps, cause problems sleeping (insomnia), or cause changes in your mood.
- These side effects will go away after you start taking less of the medicine, or when you stop taking it.
Your doctor may check your blood counts regularly.
