Hi. I'm concerned because my CEA level has increased to 1.0 from 0.7 in my latest blood test.  Itr also increased from 0.5 to 0.7 in the previous test 6 months ago 

Has anyone experienced this?  I know it's still within range, but the increase is worrying me.

  • Your CEA can bounce a bit if you took it twice in one week as far as I understand. My mum has had many CEA readings and some times they pop up a little and down again .

    I am no expert but given it can fluctuate a bit I would think it’s too early to worry about it just yet.

    Its hard as anxieties can surface and make you worry about things .

    You take care ,

  • Thank you for your reply.  No, it wasn't twice in one week. It was 2 tests, six months apart from each other.  It's just that it has stayed constant for 2 years since my surgery, the risen on each of  the last 2 tests.

  • Sorry , I meant you could take it twice in one week and get two different readings .

    Has your Oncologist offered any input ? You could say that you are concerned about the increase in trajectory.

    Have you had a scan during this time ?

    You also might like to make sure they are using the same lab each time as some people have found small variations in that .

    But if you have not had a scan it might offer some reassurance to see if your oncologist feels it would help .

    My mum’s oncologist scans if it breaches the threshold or If she was increasing around the threshold .

    Not sure what age you are but inflammation and aging itself pushed my mum’s up a bit for a few years . The scans at that point were fine .

    But please do ask for an appointment.

    It gives you more answers and reassurance.

    Take care

  • Hi  If you click on my name then you’ll see that mine went from under 1 to 1 to 1.8 to 1.5. I’ve read before that it can vary like your blood pressure can? They will only be concerned if it jumps up in larger numbers. I’ve attached a link to a post from the bowel cancer uk board from a few years ago that covers CEA rises?

    Hope this helps?

    Take care

  • Thank you for your reply.  That is reassuring to know. X

  • The nurse wasn't concerned, so I really shouldn't be. I think I overreact to things.

    I had my last scan in January and was all clear.  I am 78, so it could be age as you suggest.

    Thank you. X

  • Hi. Mine was 10 then 25 and it is now 65 but I’m incurable so I suppose it’s sort of a natural progression.


  • Thank you.  Good wishes to you . Xx
