Skin Changes

Radiation therapy can cause the skin in your treatment area to become red, itchy, dry, sore, swollen, or tender. The severity of your skin changes depends on the dose of radiation you receive. High doses of radiation damage and kill your skin cells. These skin changes usually start within a few weeks after beginning treatment, and go away a few weeks after finishing. However, you may have some long-term changes, such as dark, blotchy, dry, or thick skin.

Avoid using heating pads, ice packs, or anything else that is very hot or cold
