Signatera Test. Is it truly helpful and worthwhile?

Posted by pbnew @pbnew, Nov 30, 2023

I haven’t met anyone who has used this test. Do oncologists recommend it? How does it help?

It is ductal and they didn't get all the cancer when they done my mastectomy plus they removed 5 lymph nodes that were also positive for cancer, so now it's metastatic breast cancer. The signatera test was positive

@arminda Is it metastatic to the lymph nodes only or somewhere else like the bones? Those are both very low positives. Sometimes you can get positive results with cancer cells dying off.

My oncologist and a 2nd I went to in an attempt to get the test, both argued against it for the false positives and false negatives. Said it has not been thoroughly tested for the results. The other question both had, was how do you proceed with the results? If the result is false you could either do unnecessary testing or not test when you should.

I lobbied for it very hard!!! This the 2nd opinion. But neither would agree it was worth it.
