I'm just figuring out how things work too. Like I just found your message about a week late. I guess there is some kind of setting to notify you by email if you have messages but I didn't have it checked. Sorry about that.
I had never heard the term "triple negative" used but that does sound like the kind I had, highly aggressive and invasive. Not just a contained lump but little tendrils worming in everywhere. My chemo was every 3 weeks for six rounds. I never had radiation but I hear that can be very difficult.
Keep me posted on your daughter's health if you can spare the time. My thoughts are with her and your whole family during this ordeal.
