Hi jlyneham,
i was diagnosed with TNBC in nov2016 and left breast and had mastectomy, 6monyhs chemo and 1month radiation and am 6months past the end of my treatment for that and now I have a lump that feels similar to my original cancer but in the opposite breast. They wouldn't remove the other breast as they said being brca negative there was no need to remove it. I won't know for another week or so if it's contralateral TNBC but I may be in the same boat as you in a way. How are you and did you go? Your not alone.
