I was stage IIIc. I have to be honest, I took it on the slight chance it promoted protection against bone tumors. I had all 3 years, but I am now extremely limited in the dental treatments open to me. This is significant because my lower teeth cracked, broke and eventually I had needed extractions and in the 2nd phase of restorative care. Truthfully, however, they're not sure it was the Zometa or all the chemo I had over 5 years ago now, causing the breakage, etc. Dentists don't like to treat Zometa patients: too much risk for them, so I ended up having the extractions in hospital (outpatient) which went extremely well. Zometa can put 3-4% at risk for jaw necrosis.
