I feel for you, I was diagnosed with TNBC in Aug 2023, after chemo and Keytruda I had a double mastectomy in June 2024, then reconstruction, then another round of Keytruda, then in March of this year the oncologist gave me another CT scan right after finishing the Keytruda and yup, it was back (if not the same tumor, oncologist and I are suspicious about that)...after another surgery and 30 radiation treatments I am now on Capecitabine. I had more side-effects from the Keytruda then the Chemo I was and am on currently. Right now they are doing CT scans with contrast. I have one coming up next Wednesday and am just hoping that everything looks good.
