Hello. You have gone through in my opinion chemotherapy which can be very very difficult. I am not being flippant but I found the lumpectomy and node clearance reasonably pain free and uncomplicated. The drain was a pain but that was only for a short time. It is scary having surgery. I remember crying before they knocked me out. I stayed overnight as I had major surgery on my cervical spine a few weeks before. Take painkillers when needed, rest up, no housework or heavy lifting. Just eat small light meals a few days before and after. Cancer is crap. Go out Monday somewhere with your family and friends. My very best wishes for successful surgery. Xxxxxx
