Yes, I had triple negative BC and in the month between my first ultrasound and my first diagnostic mammogram the cancer had spread from breast to my lymph nodes, chest wall, and skin.

Since it was TNBC treatment was always going to be chemo first, then a mastectomy and they added radiation post surgery because of the chest wall. I did 35 rounds of radiation, 25 whole breast and 10 targeted. I also took an oral chemo at home for a year after that.

Keep in mind that triple negative is a tougher cancer with limited treatment options, so everything is much more old school. Hopefully you will have more things that your docs can do for you.

Hugs! Keep us posted.
