Any ideas why Cea would increase while taking radiation and 5 FU? My cea has nearly doubled in 6 weeks! Hoping it's not related to a possible return of previous lung mets. They're radiating now for a perirectal mass:( Any thoughts would be appreciated! Thanks in advance!

    Dear changing,

    The easiest way to locate other members with similar experiences is to type keywords (such as "radiation," "CEA," etc.) on the search bar at the top of the home page. You can refine your search by clicking on the different categories of content listed below the list of keyword matches that you get from your search. The major categories of content on CSN are discussion boards, personal web pages, etc. For example, if you are looking for a personal web page, you can limit your search to personal web pages only by clicking on the "personal web pages" category. Remember that you must be logged in if you want to post anything on a discussion boards, view personal web pages, use the chat room, etc.

    We hope this information is useful,
