Hi Gillian, thanks for the information, Will it affect my collar bone area if it is just the breast area that is being radiated or did you have lymph nodes near there being radiated as well. The staff haven't told me about using it before treatment only on here several women have suggested they did and it helped. Hopefully I will be able to get the Moo Goo Udder Cream tomorrow and start using it. Was you radio just over four weeks from your surgery? I am finding my breast and under my arm still a bit sore inside so hope the radio doesn't make it worse. Time will tell and I'll deal with it. Maria
