In colon cancer patients, y do some hae higher cea"s (like in the 100, s) and some don't? My dad's CEA stands at 10 at present while on irinotecan

Change in level. Changes in the level of CEA are more useful for monitoring the course of disease than one reading. There is wide variation in CEA levels in patients with colon as well as other cancers.
