I'm looking for a tumor marker expert. What does Ca 27.29 and Ca15.3 measure, since benign, inflammatory conditions can rasie the levels of these markers, too. Treatment decisions based on markers...are these valid? Has anyone in the universe stayed on Tamoxifen in spite of rising tumor markers and remained cancer-free? Where is the data on this since Tamoxifen has been around for twenty years?
