Signatera blood test for recurring colon cancer

Yes. My oncologist thought it was a good idea. I go in every other month for blood draws…so far all is good.

@reidroberts, in addition to the reply from @mynightmare2022, you might appreciate this related discussion in the pancreatic cancer support group

Yes. I'm on my 6th blood draw now

I've been tested every 2 months. After chemo, radiation and surgery my first 2 tests were zero. The next 3 tests went from .04 to .06 then to 1.13. After scans last week a very small spot on my lung has shown up. So a cryoablation procedure is being scheduled now. Hopefully blood tests will go back to zero. We will see what happens. I'm glad these blood tests can detect cancer developing very early instead of dealing with a larger problem.

@reidroberts, did you have the cryoablation? How are you doing?

My signatera blood test went up to a 5 and they did the cryoablation this last Monday. They froze off a spot that is so small they cannot even get a biopsy but assume it's cancerous. They could not find anything else but will scan again in about 3 weeks. Hopefully my blood tests will come back down from doing this procedure. If not we will take care of whatever shows up. I've done 2 of these cryoablation procedures in the past and they are not too bad. Much better than surgery. So far so good and keeping my fingers crossed. Signatera blood testing seems to do a good job detecting cancer very early instead of latter when it would be much harder to deal with.
