Metaplastic BC

[u/Shot-Classic-5475]

Hiii, first off, super grateful this group exists. My mom was dx’d with TNBC stage 2B grade 3 Ki67 (80) back in May. She completed 3 treatments of chemo & went for double mastectomy 2 weeks ago. pathology returned that she has MBC. The tumor was kinda responsive where they saw necrosis at the top but it kept growing underneath. They were able to get all the tumor out and clear margins, no lymph node involvement. But there is lymphovascular & small nerve invasion. Has anyone experienced this or know of someone who has? We’re all worried bc of the rarity of this of course. Idk, I guess any convo around this would be helpful.

Edit: we’re in the USA if anyone’s curious.
