Topic: CA 19-9 vs. CEA numbers
What's the difference between the CA 19-9 and CEA tumor marker numbers? My mom's CA 19-9 has been going down, but her CEA number keeps going up (from 5.9 when she was first diagnosed to 20.5). I asked my mom's nurse what this could mean & he said it could mean various things, but only a scan would truly reveal what's going on. My mom's scheduled for a CT scan on 12/30 anyway to see if the chemo has been working, so I guess we'll find out then.
But my question is, is this something that could signal a bad news? My mom's been battling depression as it is, and I think it might be really hard for her if she got bad news on 12/30. Should I try to prepare her for it? (I've been checking her lab results, so she doesn't know anything about these numbers.) If so, how should I go about doing it?
