Could radiation therapy be giving me acne?

Possible: If the areas you have acne are within the radiation field, it is possible. The staff should be able to suggest things you can do to reduce this starting with frequent washing of the area with soap and water.

Yes: We do see an acne type rash in the treatment area at times. More commonly its just a sunburn effect. However check to see if you are on Erbitux which is known to cause a acne rash all over. Sometimes this is severe and needs antibiotics. If its just radiation, we have creams that help and washing with an antibacterial cleanser is very useful. After the radiation these skin changes should clear.
