I know that on the web it says that CEA levels of 2.5 for non-smokers and 5.0 for smokers are considered normal. It also mentioned that there are a few different ways to measure cea levels. My CEA is 3.4 - I live in Boston and go to Mass General - I was stage 3. I just had it done. My doctor said that anything below 3.7 (at MGH, apparently) is considered normal. I have never smoked and apparently mine has been around 3 for quite some time. I am currently NED. I had never thought about this, but all of you with CEA's of .5, etc. This is making me a little nervous. Any insights? Anyone else have a "normal" for them CEA that is a little higher?
