Hi Victoria! I am on day/unit 14 of 15 rounds of radiation. I found that my throat began to hurt on around day 9 and fatigue began to creep up around then as well. The redness/burn was noticeable around day 5 …it gets darker as the days pass and more treatment. At the Center they said it usually begins around day 12
Overall, I found voltarren gel was helpful to cool the area although I don’t actually feel a burn - I felt some heat initially but that was minimal. It is a little itchy but nothing compared to a mosquito bite. I lotion daily with CeraVe, they provided a mouth wash which helped a bit but eating cold fruit and orange juice felt soothing.
-stretch as it will become tight, moisturize, rest when you need to as the fatigue for me crept slowly, and stay hydrated as best you can. Wishing you the best of luck!

Good morning and welcome Victoria, like everything else from healing after surgery, chemo, the hormone blocking drugs every womans reaction is different. From what I have mostly read here, burns happen closer to the end of treatment and up to weeks after treatment is done. Radiation is drying, moisturize constantly and stay well hydrated. Many women who had radiation have said what has worked for them. There is nowhere better to find out what works than right here from women who have gone through it. Breast cancer sites will point to a product they are promoting, hearing from real women is where you will get reliable information.

Thank you so much Ella. Your information was very helpful. It helps if there are no surprises.
