I am interested in finding out what the difference between a CA127 blood test and a CEA blood test in regards to measuring cancer antigens. Also interested in what they should be showing in order to show progress is being made in treatment, or if something is wrong. My sister has been fighting breast cancer for 4 yrs, never in remission...but has now found a lump in her other breast. The antigen levels seem to be going down, so I don't know if I should be alarmed or not. I hope someone can help.
