Today we are interested in the most common side effect of radiotherapy: radiodermatitis.
What is radiodermatitis?
Caused by the ionizing rays of radiotherapy, radiodermatitis is a skin inflammation that resembles a bad sunburn: the skin is red, dry, hot, swollen, then it begins to peel. In the most extreme cases, symptoms can go as far as ulceration or even necrosis.
Is radiodermatitis temporary?
Generally, yes.
Radiodermatitis appears more or less quickly over the course of the radiation sessions, and it disappears on average within 10 to 15 days following the end of the sessions.
But in some cases, it can become chronic and requires lifelong monitoring.
How to treat radiodermatitis?
To soothe the skin, you must first hydrate it well. The radiation oncologist prescribes an emollient cream to apply after each radiotherapy session, preferably in the evening. To avoid it being painful, it is advisable to lightly touch the skin. To relieve the feeling of overheating, you can apply a handkerchief soaked in soothing and anti-irritant thermal water. Or put a cold pack from the freezer on the painful area, a packet of peas can also do the trick.
Above all, do not leave the bag in direct contact with the skin! You must first wrap it in a cloth.
In the event of significant irritation or oozing, notify your radiation oncologist, he will prescribe appropriate treatment or fatty dressings.
If you wish to call a fire cutter, also inform your medical team.
Are there any other precautions to take in case of radiodermatitis?
Do not go out in the sun for a year after radiotherapy has finished.
And remember that irradiated areas should never again be exposed to the sun without sun protection!
