I have had exactly that. I also finished end June and breast is fuller and harder than the other one and quite sore but not unbearably so. I also have a bruised feeling in ribs below. My BCN checked it out and said breast odema.
Hi all I finished rads at end of June
My breast became very swollen during radiotherapy and it has not lessoned.
Now inside is getting harder and harder, I also have an egg shape lump form under scar where lump removed.
Its very noticable how much larger this breast is to other.
I assume all this is internal scarring from rads, and maybe scar tissue has formed around fluid in breast.
Have any of you experienced this in the months after rads?
I see oncologist in couple weeks, called BCN who said she would arrange a scan but she never did as totally swamped with workload and few staff.
I have given up trying and will wiat to see oncologist but am a bit worried.
