    Hi zazi2010,

    I am sorry for the delay in my reply. When exactly did you last see this doctor and did he/she perform the cea test?

    I have a link to a wonderful summary on the Carcinoembryonic Antigen (CEA) test that can explain CEA levels in more detail. The second page is going to be most helpful to you in looking at reasons for High Values as well as What To Think About shows information that you need to know about possible recurrent colon cancer.


    Please make sure to follow up as soon as possible with your doctor again or even get a second opinion if you feel that you are not being fully treated at the moment.

    I wish the best for you and hope that you will keep us posted! You are in my thoughts and prayers.
    Best Wishes! Amelia

    I've been going through this with my wife for the last year and a half (stage 4 rectal cancer, currently on chemo) so I've been doing a lot of research.
    Be sure to check your thyroid activity-it can affect the test according to what I've heard.

    can you give some URL's to read?

    and explain what you mean by thyroid activity?
