Hi Trina
There is a post that is only a month or so old on here that you can search for and I have put down my thoughts and advice.
I went through 35 treatments of radiotherapy (7 of them being booster zaps directly on the tumour site) and only I finished on 5/9. I had minimal problems with a very small blister which lasted a day or so. My skin did go very red especially in the area of the booster zaps but no blisters, peeling etc.
I used Sorbolene cream only and it worked wonderfully well for me. I do still have my breasts which I am not sure whether that does or doesn't make a difference to burns or not.
Hope you can find the other post as well.
Wishing you the best and hoping your skin comes through unscathed like mine. It is definitely a walk in the park after horrible chemo. You do need to take good care of your skin though and watch out for any clothing which may rub on the area and irritate it as that is a major factor I feel. I wore loose singlets.
The public hospital I went to provided as many tubes of Sorbolene as I needed which was great as it was one cost I didn't have to worry about.
Hoping everything goes really well for you.
Mich xoxo
