@valleymom I may have said this before, but I used three creams for my three weeks of radiation and my breast is soft ...really, no problems. Fruit of teh Earth gel, Miaderm1 and Aquafour. You can get all three on Amazon. I took a baggie of teh gel with me each day and when I got back in the dressing room after treatment, I slathered the breast with it. Then at home, I rotated the three creams every hour or so. Use these for at least two weeks after end of treatment too. I had some itching at very end and doc prescribed a steroid cream. Took care of it pronto. The breathing was tricky for me at first. (This was entire right breast and I had to breathe and watch the bar go up on a screen,) I went online and found a video to help me and then it was easy. I'm on a blocker, anastrozole, and so far I've been lucky (18 months on it). No problems. Fingers crossed. But you can always change if you run into a problem. I was stage 1 b. lobular. And I read everything I can about it! I hope some of this will help. Welcome the treatment, and I know that's hard. That's the only way. Women in the 1950s had such a tough time with very few options.
