Hey Vicki

I wasn't sure it was you at first. Tumor markers are very, very unreliable. CEA can easily go up if you have had just one glass of wine the night before (so a tip is to not have any alcoholic drinks the night before). The CA 15-3 is even more unreliable than the newer CA 27/29 (and in reality, with the CA 27/29, there is no difference between the two readings you had there at all). If you don't want the wait, you can always ask for the bloodwork to be repeated in a month instead of two months. Infection and illness or being slightly allergic can also alter the results.

I am thinking about you and smiling.

Love, Becky
