Are you inferring that because my ca19-9 is increasing even though it’s under 37 is indicative that something is growing? Is the ca19-9 suppose to stay the same or decrease after surgery/chemo?

marienewland,

I don't know that the question can be simply answered - most explanations of CA 19-9 testing indicates that a number over either 34/37 (depending on which test) may indicate you have a cancer, and that a number under may indicate you may not have a cancer. It is used as one of several tracking tools.

I can't find much to indicate whether an increase in someone without cancer from say, 12 to 18 means much of anything. However, if it were to increase from 12 to 200, it may mean something, but this is not used as a diagnostic tool in most cases.

My basic understanding is that under 34/37 should be expected in someone without cancer. My sister's CA 19-9 decreased from a high of 2000 to 46 during her chemo treatment, but was never under 34/37.
