Good luck tomorrow. When my Signatera test showed up positive the second time with a very small number, I was hoping it was just a false reading. Unfortunately my Oncologist told me they have never had a false result with Signatera tests. And with the low numbers I was hoping it would take awhile to develop before I had to remove it. However, the tests elevated quickly, within 2-3 months, where we could see the spots on a scan and then have them removed. This sucked but after all said and done, I'm fortunate to find these early. It's much easier to remove a 1/4 inch spot than a 3 inch tumor. So, my next question for the Doctors is if the Signatera test come back positive in the future with a very low reading, should we do a few chemo rounds to knock it out before it can develop into a very small spot.
