Hi MD. I totally get where you are at right now. Like you I have a watch and wait lump under my left arm just underneath the original scar line. I have had it scanned and biopsied and whilst it's "OK" right now it worries me constantly. I sometimes wish my surgeon would just go ahead and remove it but she doesn't want to do anymore surgeries unless really necessary. So for now, I check it monthly, have it scanned yearly and hope and pray that it continues to be OK and doesn't have a change of heart and become a nasty lump.

Hang in there.
