i posted a few months ago that my husband casey's dr said he is in remission, but his cea tumor marker was elivated and he would keep an eye on it. it has gone up again. i didnt know the numbers last month, but now i do. it was 180 in july and is 225 now. i did a search on the site and some people have 2 or 3 as their marker. is there more than one way to measure this thing? if not, then 225 means pretty active cancer i'm thinking. i am open for education.
