It was more than 80 percent correct in spotting cancerous nodules, but accuracy still needs improving

No it doesn't mean that it has metastasized, nor does it mean it has not metastasized. What it is, is a tumor marker that with other factors can be used to estimate the stage and extent of disease or "tumor load." Once a base line is established and treatment begins a decrease is a positive indicator that treatment is working and an increase is a negative indicator.
Your mom's is slightly elevated but it doesn't mean much in isolation from a lot of other facts. With that said, if it has metastasized and she were being evaluated for surgical treatment of metastases this level of CEA would probably be viewed as a positive prognostic indicator.
Let's hope it hasn't metastasized but if it has don't let it knock you off balance. There are a lot new treaments, a lot of long time survivors, and yes, more and more of people getting cured even after a metastasis.

There is some info on CEA that I haven't been able to find (google) anywhere: How does the CEA value grow? I have understood that the normal CEA value is between 0 and 5. Some people consider values such as 27 very high. Some are truly panicing at 250. But what about the CEA values of over 3000, over 4000, over 6000, even over 9000 you sometimes see...?? I know some values grow exponentially (20, 40, 80, 160, 320, 640, 1280 etc), but how does CEA value grow??
