What are normal CEA levels for different cancer stages?

CEA levels can vary widely between individuals and aren't always directly tied to cancer stage, as factors like smoking, other health conditions, and individual biology can influence these numbers. Many community members find it helpful to discuss their specific CEA trends with their oncology team, who can provide the most accurate interpretation based on their complete medical picture and use these levels alongside other diagnostic tools to guide treatment decisions.

Mine is 3.5

Mine is down to 2. I'm on second line therapy with folfiri. Liver values have spiked, though.For some reason, and they want to find out why. It is weird that the cea is going down, but the liver values are going up. They are trying to exclude lifestyle factors.But they are going to be getting imaging soon.
