Waste of time and $$. I had the Signatera test done 7 times - every time in came back negative. But guess what? My TNBC had returned but the test said negative!!! No more Signatera for me and my oncologist agreed!!

Very concerning! I’m sorry you had false negatives ( known risk with test). Definitely cannot be the only thing one relies on. Symptoms ARE EVERYTHING and we need to be hyper vigilant regarding this dreaded disease!

I hope you are able to get the treatment you need to address this recurrence. Best to you🌸

So sorry to hear that. Is it ductal or lobular? Is it from the same site?

I was told that if there were cancer cells missed untreated at the original site, there may not be circulating DNA cells in the blood stream. In which case, the Signatera test would be negative...
