ctDNA test

Three years post treatment and my mind keeps worrying that it’s coming back. I have heard of a blood test that is available privately which is so sensitive it can detect if there are any cancer DNA proteins ctDNA. I was wondering if anyone else had used this test and then I worry that do I really want to know that it’s still lurking there. Would a positive test just make me feel more anxious or would it make me feel in control of the cancer. Any thoughts much appreciated x

Sorry can’t help but interested in answers. I think I’ve seen this on the American sites some people have mentioned it but then said no one seems to know what to do if the test shows something. I worry constantly about recurrence but don’t know if this would help or not .

I don’t know about this test, but if available, what would happen with a positive test, If there were no other indicators?!!
Also, there is probably money in it for someone somewhere.
There would have to be a care pathway in place to address this, but there’s probably little evidence to do so now.
As ever, worrying about something that statistically is less likely to happen doesn’t change anything & only makes us feel worse. Mind you, it would be nice if we could just switch off the worry circuit!
