Kat,
I will soon finish my one year of herceptin and will be talking with my onc about second year. A lot may depend on the two year results of the HERA trial. Currently no tumor markers are done, as my onc feels that they are somewhat unreliable and looks more at symptpoms, etc to determine further scans, tests, ect. He does blood work for bisphonsphonates(sp?), liver enzymes and I have had a cat scan that came back all clear.
Sassy
