Ct Scan Ok But Cea Level Rising Again?

Hi,

my husband just had a scan because his cea level keeps rising. His cancer is stage 4 with mets in the liver and the cea had been going down for 9 months. The last 4 chemo sessions the level has continued to go up. The doctor said that since the scan shows that the lessions in the liver have continued to shrink and that there it has not spread any where else that we will need to use another marker to follow the progress.

Has this happened to anyone else? We are so relieved to hear the good news about the scan but still worried about the cea level.

thanks Googie
