Tumour Marker Question

Living with secondary breast cancer Supporting each other and sharing experiences

Hi All

I went to pick up a print out of blood test results today from the nurse, the tumour marked results weren’t back so she started to write the ones from 2 weeks ago on, then realised the new ones were back and printed them instead… I noticed that the CEA had gone up from 3.2 to 4.7 in 2 weeks, that seems like a lot? My question is; is fluctuation normal? 

Thanks

littlep, I’m going to tag along with you on your question. I just received my CA 15-3 results while awaiting scheduling of a PET scan to further investigate bone/lung met possibility. My score was 58. I don’t know how this rates on a “not too bad for a starting point” or “up there but might drop once treatment starts”. Anyone understand the numbers. IDC grade 1, stage 2 before they saw MRI/CT suspicious bone and lung pictures.
