Herceptin and CA 27.29 tumor marker
Does anyone know how Herceptin makes the CA 27.29 tumor markers react?
I get everyone is different--but my understanding with chemo is that it elevates this marker--and that after chemo it is suppose to come down--my question is.....
Does Herceptin elevate tumor markers?
Thanks----
