Alleviate irritation

How can I alleviate the discomfort caused by radiotherapy?

The rays produced by radiotherapy can cause skin lesions known as radiodermatitis. Symptoms range from simple redness to severe burns with ulcerations.

Radiotherapy actually caused burning under my breast. I was on the verge of stopping the treatment, but I was advised to try applying cream after the radiotherapy sessions. That was precious advice.

Our advice

  • Protect the treated area from sunlight. If your skin is exposed, apply Avène SPF50+ broad spectrum sunscreen, 20 minutes before going outdoors. Reapply it every 2 hours, or more often in case of swimming or sweating and immediately after towel drying.
  • Adapt your daily skin care routine, in particular to the irradiated area.
  • Use emollient creams after the radiotherapy session, never beforehand. Apply gently, by tapping delicately.
  • Apply an emollient cream as soon as you begin radiotherapy, before you start to suffer from radiodermatitis.
  • Wear loose-fitting and comfortable clothing.


  • Irradiated skin is more fragile, sensitive and prone to bruising, even after the end of radiotherapy treatment. Symptoms can last for several months and even years. Thus, your skin requires continuous monitoring and care.
  • When radiotherapy is associated with certain chemotherapies, the appearance of radiodermatitis is more common.
  • As demonstrated in published clinical studies, the twice daily application of Cicalfate Restorative skin cream was able to help reduce symptoms of radiodermatitis, thus improving tolerance to radiatherapy treatment.
