My sister was diagnosed with tnbc in 2022. In remission since January 2023. In March 2026 she got a positive Signatera test, although low 0.20, still positive. Scan does not show a tumor yet. Has anyone had this happen? What didbyou do going forward? She sees her oncologist next week and she is figuring she'll have to wait and see for a tumor before they begin any treatment.
