Topic: Confusion re tumour markers?
I am very new to all of this, as my mum has only recently received her diagnosis of ICC. Initially we believed that the mass in her liver was benign as all of her tumour markers were within the normal range. I was wondering whether this is a common occurence? I have read a lot on this site about CA19-9 and CEA being raised in CC. How is it that someone could be at an advanced stage of this cancer and have normal tumour markers?
Many thanks to you all. This site is so helpful and reassuring.
