My husband had his colon surgery July 24th 2019, finished chemo March 2020. His CEA was 4.9 at time of diagnosis and then has been very low since his surgery, .5, .6 and then in Sept was undetectable. He has been having some pretty bad lower and middle back pain. He went to an orthopedic dr and had some some xrays and an MRI done and now has been referred to a chiropractor within his clinic. The scare it could be cancer asked the orthopedic dr and he said there is nothing that indicates that but said we should contact his oncologist for reassurance so we did. She said it was highly unlikely but said he was due for his CEA labs so he did those. It has risen from undetectable to 1.2. Is this something to be concerned with? His oncologist does not seemed concerned and said it was within normal. I can't help to still be worried. Can other things cause an increase like this? The oncologist made an appt with him as a follow up as I guess it was time and she said they can talk more about his back pain. I'm just so scared right now. Any insight on this would be appreciated.
thank you
