Yes. The following guidelines will help minimize skin irritation during radiation therapy:
Try not to scratch, rub or scrub the treated area.
Do not use any soaps, lotions, deodorants, sun blocks, medicines, perfumes, cosmetics, talc powder or other substances on the treated area within 2 hours of treatment.
Wear loose, soft, cotton clothing over the treated area. Avoid tight-fitting, scratchy clothing, which can irritate the treated area.
Do not apply heat or cold to the treated area.
Avoid hot or cold water (including heating pads or ice packs). Wash the treated area with lukewarm water.
Protect the treated area from sun exposure.
If you must shave, use an electric razor on the treated area. Do not use shaving lotion or hair-removal products.
Do not use adhesive tape on treated skin. If you must bandage the area, use paper tape and apply it outside of the treated area.
