Hi - I had 5 sessions of radiotherapy to my left breast a month ago. I am still swollen and blotchy but the skin is not broken. I use Aveeno constantly. How long do these side effects last? My review said side effects should improve about 2 weeks post treatment but it seems to be coming and going still a month later.
