skin mets in the form of nodules

Hi there, I just had a question as to what exactly is Navelbine? I've heard it used on here a couple of times. I am currently on Xeloda with Herceptin infused once every three weeks. My Xeloda is taken 2150mg in the am and 1650mg in the pm. I had skin mets to area of origination, mets to lymph nodes under left arm and under right arm. The Xeloda seems to have shrunk nodes under both arms and I can only pray that it will prevent mets to an organ but, don't really know if that is possible. Would Navelbine be an option for me. I have IBC and I'm HER2Pos.
