Hi when they do a test before your oncologist appointment eg CA15.3 what should the count be? mine has gone from 42 down to 36 like to know more about these tests ????
I finished treatment in September last year, I don’t remember having any tests for blood cancer markers. Did your oncologist suggest these tests and how often do you have the test. If you are concerned definitely call up the oncologist, they might be able to give you more information.
