Tumor Markers

horselover13

I was hoping someone could help me. I had breast cancer in 2004. Lymph nodes were clear. Almost made it 5 years. However a few months ago, I found out it had matastisicized in my hip bone. I changed meds about a month ago or so from Temoxifan to Femara. Completed 2 weeks of radiation 2 or 3 weeks ago and have just finished my 3rd treatment of Herceptin and 2nd of Zometa. I have to do the Herception once every 2 weeks and Zometa once every 4 weeks for at least a year. Does anyone know when I should start seeing the turmor marker go downward?

Thanks, Karen
