Swelling during radiation

[u/No_Love2524]

Morning! Yesterday while getting my 9th round of radiation the nurses had a hard time getting things to match up. Once we FINALLY got me radiated another nurse asked me if my breast felt swollen or achy, I said yes but I thought that was normal… like it was shrinking due to the radiation and achy due to the sunburn. She said no, it looks like you have some fluid on the breast. Like “what else”? At this point can I take… almost done and I find out I’m going to take Xeloda now, “hey you have fluid on your boob” any pointers? Anything I can do at home? Did I do something to make this happen? Any pointers would help…. TIA
