For rads I was told only sorbolene which I did as I went, everyone is different, I burned and blistered all over the breast and under my arm at the end. It healed super quick thankfully as it was difficult. The worst thing was the fatigue from radiation, I was forced by the radiologist to have 2 weeks off as I worked all the way through rads. 4yrs later a recurrence! and chemo ummm didn't fair so well, had to give up work, its a beast! x Everyone is different, the staff are great and will advise you every step, easier than chemo, just a nuisance every day but not weekends.
