Why has my skin changed?

Skin cells divide quickly, so treatment reaches them too. Radiation can make the treated area red, dry or sore, like sunburn. Some drugs cause rashes, dryness, or changes in nails.

Show your team anything new rather than treating it yourself, because a few rashes matter more than they look. Ask which creams are safe, since some products make radiation skin worse.
