I thought I’d add the creams that I used for anyone who might be interested. My radiation oncologist recommended a cream called Biafine, which I had to get on Amazon. I used it right after each session and then at bedtime. After about 6 treatments, my nipple became very irritated, so he told me to use Aquaphor on the nipple and surrounding area twice a day in addition to the Biafine. The following week, underneath my breast got extremely red, so he gave me Silvadene cream. He told me to use the Silvadene on the red area underneath my breast and at bedtime to put the Silvadene all over my breast. At that time, I also started using the Biafine 3-4 times a day instead of only twice a day. Right before my last treatment I developed a rash on my chest, and he gave me hydrocortisone cream to put on that when needed. A day or two after my last session, my armpit got extremely red and painful. I liberally used the Silvadene on my armpit, underneath my breast, and any other area that was red. About 12 days after my last radiation session, my skin started to get better. I am now 3 weeks post radiation and it is much better. I still use the Biafine in the morning after I shower and at bedtime just to keep the area moisturized. I never did blister or have any open skin. I had radiation in the prone position. I was very nervous about that since I never ever lay on my stomach, but it actually worked out fine. The hardest part was figuring out how to get on and off the table. It only took a couple days for me to get a system. One last thing, I used Dove Sensitive bar soap for showers during radiation and am still using it.

@marshgirl24, thanks for the follow-up and sharing what worked for you. This will be really helpful for members who read the discussion about Skin Care During Radiation.
