What is radiodermatitis?

Radiodermatitis is a significant side effect of ionizing radiation delivered to the skin in the process of cancer treatment and nuclear attacks. Erythema, dry desquamation, and moist desquamation are all the forms of radiodermatitis.

For now, given the current technology strength, the side effects of radiation therapy still can’t be completely ameliorated.


Within a short period of time, the skin of the patients with the condition may have erythematous rash, desquamation, and necrosis.

Late effects may include pigmentation changes, telangiectasia, photosensitivity, fibrosis, atrophy, and delayed wound healing and other complications of surgery within the radiation treatment field.


Radiodermatitis has something to do with lots of factors, such as radiation dose, chemotherapy and radiotherapy durations, and the normal tissue sensitivity of individuals.
