Did you develop lymphedema in your hand or arm after breast cancer AND before radiation? Evidently this is pretty uncommon, and yet I have it. I’m supposed to do radiation still (now postponed by one more month), which is known to cause damage that can cause lymphedema. I’m trying to find others who had it prior to radiation to see if it made them worse. Apparently, the are no research studies on this. I am in a huge soft cast from fingertips to shoulder. Typing is difficult! Send me an email via Contact page please.
