Hi,
Just got very scary news, and I'm hoping someone can help me understand.
My Mom is Stage IV and just finished her 6th chemo treatment. Her CEA started at 2400, and has been steadily coming down. By treatment 5 it was down to 500. Then suddenly it just jumped to over 900. Does anyone know if this could be a mistaken lab result, if CEA can really jump that much, if it means there's likely another tumor, if there's any way to turn the CEA around once it starts going back up, etc? Thanks for anything you can tell me -- I am so scared this is a very serious turn for the worse.
