What should you know about radiation skin care?

Radiation can make the treated skin dry, sensitive, red, itchy or darker or lighter than nearby skin. The reaction is usually limited to the area receiving treatment, but its timing and intensity vary. Friction, heat, adhesive dressings, strong fragrances and unapproved creams can add irritation. A rash outside the treatment field may have another cause, such as Contact Dermatitis, Heat Rash, Intertrigo, Atopic Dermatitis, Psoriasis, Ringworm, Scabies or Drug Rash; the appearance alone cannot identify which one is responsible.

Wash gently with lukewarm water and a mild product approved by the treatment team, then pat rather than rub. Keep the area protected from sun, heat, tight clothing and scratching. Use only creams, dressings or deodorants that the team has approved for that site and treatment. Keep the skin clean and dry where folds touch, and tell staff before applying anything over treatment marks. Do not remove markings or use exfoliants on the area.

Contact the radiation team if redness is spreading, pain is increasing, skin is blistering, peeling or open, or fluid is leaking. Fever, pus, a foul smell or rapidly worsening warmth can signal infection and needs prompt assessment. Seek urgent help for facial swelling, breathing difficulty or a sudden severe reaction. A new rash beyond the treated field should also be reported rather than self-treated.

Which cleanser and moisturiser are suitable? When may I apply them? Should I avoid deodorant, shaving or adhesive dressings? What does a normal reaction look like for my treatment? Who should I contact after hours? Could a rash outside the field be a separate condition?
