I have been diagnosed with HER 2 and estrogen positive breast cancer and been treated with chemotherapy and Herceptin. My oncologist has recommended a five-year treatment of Femara; however, I have high blood pressure (norvasc), osteopena (sp) and high cholesteral (pravachol). I really don't want to take fossamax or any more drugs than necessary, but also do not want a recurrence of breast cancer. Is there a clinical study and shows femara vs placebo rather than femara vs tamoifen (novartis trial)? What is the general recommendation? Can you stop femara if side effects become a quality of life issue? Thank you.
