Has anyone ever had their CEA rise then fall on its own?

[J.T.]

I'm in remission but my cea has been rising and is now at 8.2. I'm going to have a scan soon to see what going on. Since it has been rising the fast few times it was checked i'm convinced that it is from a recurrence of CC but is there is a chance that its nothing. Is it even possible to show a pattern of going up and be nothing, and then go back down. Has anyone ever had it rise like this then had clear scan and have it fall back to normal? I guess i'll know more after my scan.

JT,

In late 2007/early 2008 my CEA went down on its own, but I had a recurrence. The first test came back at 11. The next was 9.6. and then finally 8.6 before treatment. I attribute the decline to changing my diet and exercising more.
My oncologist's rule of thumb is above 10 something is definitely going on, between 5 and 10 something might be going on, and below 5 takes multiple tests to see what the trend is.

After surgery to reverse Linda's Illiostomy her CEA rose up tp 16.5 over several months. She was still having chemotherapy at this time and it had caused damage to her liver. After she went off therapy it slowly dropped over several years back to the normal range. She had multiple scans during that period which remained normal. There is a high likely hood of recurrence when it goes that high but it can happen for other causes.

When dxd my CEA was 4.0. After surgery it was 2.0. When I started chemo, my CEA began to rise. Over 3 momnths it went to 6.9 and my onc ordered full scans, PET and CT which found nothing. Slowly, the CEA fell again to around 2.0 where it has remained for the past 3 years. THis NOV will be 4 years since dx. I envy people with the 0 CEA or the "less than 0", but my onc says I'm ok.
