I had the same. I had chemo first too, and had cording before my operation. I asked the oncologist, who said it was cording and I think it had to do with the chemo, but she was not worried about it. It disappeared, and sometimes comes back.
... have developed cording now after a tender axilla / upper arm since weeks and this is before my MX and node clearance. I'm having chemo just now pre op. I had two core biopsies in my axilla back in Nov where they tested pos nodes, a couple were enlarged in the ultrasound at that time.
Anyone else had this and why is this happening pre op?
