I also had TNBC. Chemo, then surgery (all clear, except some minimal lympho vascular invasion). The double mastectomy I had may be helpful to clearing the lympho vascular invasion. I then had another round of chemo (Taxol/carboplatin). I was also dealing with ATM gene. The new protocol is to test all TNBC for gene mutations. I too have the numbness in my toes and I wondered about the glutamine supplements. First I have heard about this. What brand and dose? Thank you!
