I was diagnosed late 2021 and that was before Keytruda was approved as included in the protocol for TNBC with BRCA mutation. But my treatment was somewhat similar. I had chemo first (1 every 3 weeks - 4 treatments) then weekly for 12 weeks; thankfully good response to chemo and lumps shrunk, then it was bilateral mastectomy; but since miniscule amt found in lymph node pathology - 3 weeks of daily radiation. Now I'm on Lynparza - hopefully only for a year. I just started and so far no side effects; but I've heard side effects may not appear until close the end of the first month of usage. We'll see.
