Has anyone tried Signatera testing for cancer?

Curiosity about Signatera, a blood test that looks for circulating tumor DNA (ctDNA), comes up often in the triple-negative breast cancer community, and asking about it is a great way to advocate for your care. Whether it makes sense varies from person to person, so bringing it up with your oncology team can help clarify if it fits your situation. Members who have experience with ctDNA testing are welcome to share their stories here.
