You are in the hunt. The drug itself does not cause bone loss. Estrogen depletion causes bone loss. Anastrazole deprives your cancer and therefore your body of Estrogen. In young women who would normally be premenopausal, it starts the process early and leaves the body without the normal protections to bones and heart, and other organs. There are ways to mitigate the bone loss. Zometa is certainly one of them. Walking is another, and of course calcium and Vitamin supplementation is another. Did your doctor recommend Zometa for you with your anastrazole? Did you decide to take the anastrazole?
