8 weeks ago I had a mastectomy and 3 lymph nodes removed. As I am very swollen especially on underarm and upper arm I have become concerned about the possibility of lymphodema developing. My breast cancer nurse just says this is normal healing , but my concern is that if there is the beginning of lymphodema I want it dealt with before it gets worse. I had thought of body brushing but don't know whether you should do it down your arm or up - or even if it would be any help at all. I am hoping I don't get it but I am trying to avoid it if I can - any advice please?
