I read the two comments about a dip and thought what dip? I had 6 nodes biopsied so I just had to go check in the mirror and sure enough the two armpits are not symmetrical, but the dip never caused any issues for me obviously. I’ve had issues with cording instead especially after my chest wall tumor resection so maybe that’s why I never noticed.

For the record, my breast cancer recurred in the chest wall 7 years after my DM so be sure to ask a lot of questions about the full treatment plan. I’m 4 years out from that and still taking Kisqali and Letrozole indefinitely. So far so good.
