i finished 3 weeks of radiation 5 days a week , a couple of months ago . it went very well , looked like a bad sunburn at end, but cream from nurse worked well , no pain whatso ever , no itching . healed very well . and i'm in my 60 s. with badly sun damaged skin to begin with . you will be fine , did seem to make me tired weeks after . but everyone is different . i'm glad i had it , as several lymph nodes affected . i found it a breeze . had had a mastectomy a few weeks before, so had scaring from that , but the radiation didn't worry the long scar. or inflame it . skin slightly darker a few weeks after but returns to natural colour pretty quickly . so try not to worry , don't be anxious that's a lot worse than having it done . remember it's killing off stray cancer cells . all the best .
