Letrozole(Femara) +Zoledronic Acid (Zometa)

I have been on Letrozole for 5 years now and have just completed my 6 six monthly infusions of Zometa. I had some aches and pains in the beginning but just now have a bit of stiffness but that could be from getting older. After the first Zometa infusion I had flu like symptoms for a few days but nothing with the rest. My oncologist says I may need a yearly infusion from now depending on my bone density so am due to have another scan. Those side affect sheets do seem scary but serious side affects are rare so I wouldn’t take too much notice. My oncologist also mentioned there is new research to show that bisphosphonates may prevent bone metastasis.
