I am interested to hear from folks who have this specific sub type and compare notes. I was diagnosed 6/2021 with L. Breast Ca Stage 11B, 2 positive nodes. Ki-67 90%. Had neoadjuvant TCHP x 6 July’21, double mastectomy 11/21, (tissue expanders, exchange to implants hopefully November 22) followed by Phesgo every 3 wks (will have final dose in August), rads x 25 to L chest, axilla and supraclavicular nodes.
