femara benefits vs side effects

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.

Dear puggins, We cannot give specific advice about a treatment plan on this forum.  Decisions need to be made in context of a persons individual situation, the risks and benefits in your individual situation need to be discussed with your medical oncologist who has all of the particulars of your situation.

Of course you can stop Femara if the side effects become too much to deal with. I have stopped Arimidex after three days, Femara after 28 days, and now Aromasin (?) after only three days as well. (And I did not take this lightly, believe me!) But you have to try something before you can make a decision the stop?
