Laura, CA 15.3 don't react the same way for everybody. Sometimes they don't even react at all even with mets. So if they fluctuate slightly it means nothing. HOWEVER, in my case I was always around 23 and then it went to 25 and then to 28 and 30. (I had them checked every month).Not much of a variation but the trend was bad and I jumped up and down until I got a Pet/Scan that showed mets in the liver. It was 4,5 years after diagnosis. So if there are just fluctuations, there could be different reasons, do not worry but if there is a trend, then have it checked. Hugs. Michka
