Radiodermatitis
What is Radiodermatitis?
Radiodermatitis is a skin condition that is caused by long-term, repeated exposure to radiation. It can involve reddening, itching, burning, blistering, and peeling of the skin that may sometimes lead to chronic skin changes and even pain. It is also known as radiation dermatitis, radiodermatitis, or xeroderma.
Symptoms of Radiodermatitis
The symptoms of radiodermatitis depend on the amount of radiation exposure and skin type. The rash may have the following characteristics:
- Red or brown discoloration of the skin
- swelling and tenderness
- dryness and scaling of the skin
- blisters, peeling, and cracking of the skin
- itching and burning sensation
- open sores or wounds
Causes of Radiodermatitis
The cause of radiodermatitis is long-term, repeated exposure to radiation. This can happen with radiation therapy for cancer or other conditions, or from long-term contact with radioactive materials. People who work in the medical field or nuclear power plants may also be at risk of developing radiodermatitis.
Diagnosis of Radiodermatitis
The diagnosis of radiodermatitis is based on a physical exam of the skin and medical history. A biopsy may be necessary to confirm the diagnosis. The doctor will also consider the level of radiation exposure the patient has received.
Treatment of Radiodermatitis
The goal of treatment is to relieve the symptoms and prevent further skin damage. Treatment may include:
- topical ointments and creams to relieve itching and burning
- lotions and other moisturizing products to protect the skin
- antibiotics to treat any bacterial infection present
- corticosteroids to reduce inflammation
- radiation shielding garments to protect the skin from further exposure
Prevention of Radiodermatitis
The best way to prevent radiodermatitis is to limit exposure to radiation. People who work in the medical field or nuclear power plants should wear protective clothing and take steps to reduce their radiation exposure.
