Hi @Nads I finished 20 sessions just before Christmas. Every day after radiotherapy when I got home I would cut up an Aloe Vera plant and spread the gel over my breast. I kept it in the fridge along with my sorbolene cream so it was nice and cool when I put it on. Later I would use the sorbolene. I have fair skin but I didn't get any blistering just a nice shade of dark pink. I really think the Aloe Vera helped. I have a few pot of it growing and I've always used it for burns from the oven or iron and it seems to stop the blistering and scaring.
Good luck with your treatment.
