You are being treated alright. The principle is to use chemotherapy drugs and hormones in sequential fashion i.e., one after the other. Currently you are on femara and navelbine combination. This should be continued as long the disease is under control. Once there are signs of progressive disease, following options exist:
1. xeloda
2. caelyx
3. aromasin
4. medroxyprogestrone acetate
5. faslodex
6. herceptin, if you are her-2neu positive.
