Don't think I'm real sure what this number represents.
When I started treatment my number was 103 then it went to 44 then 9.6 then 7.6.
Doc checks it once a month and says it's a good marker for me since the last scan showed 40% reduction in liver tumors and significant reduction in rectal cancer.
Yesterday at my appointment doc said he expects either this check or the next check I would be in normal range.
My question is if cea does get in normal range what does that actually mean since I will still have two liver mets and the cancer in my rectum.
