So here's an update on me. After 5 months of not wanting to start AI hormone therapy, I finally started Anastrozole. Basically, my oncologist pointed out the this reduces not just new cancer in the other breast, but distant recurrence as well (metastatic cancer-- lungs, brain, bone, etc). That scared me. I am now 7 months into the drug, and I do have side effects-- joint pain (hip, knee), more frequent headaches. But my biggest fear is still the erosion of my bone health. I'm planning on getting my next Dexa scan sooner than 2 years (even if I have to pay for it) to closely track if this drug is damaging my bones. I have advanced osteopenia in my lumbar spine, and really nervous about it progressing to osteoporosis, given that I have several friends with osteoporosis, and they have fallen, broken bones, and needed surgeries. I don't predict that I will stay on this med for the full 5 years, and I am also afraid of Zometa infusion, which I understand isn't tolerated well by some.
