I agree with japdip regarding your initial question. I have been taking tamoxifen since April 2009 with the only side effect about 2-3 hot brief flashes a day. The only way to know how you will react with side effects is to try the drug and see. Many women do not have much problem with tamoxifen. However, you may also want to ask your oncologist about taking an osteoporosis drug. I am currently in a phase 3 drug study which is checking the protective effects of osteoporosis drugs to help keep breast cancer from recurring as bone cancer. Early results seem to be very promising. At the very least, taking an osteoporosis drug will treat your osteoporosis. If there is an added benefit - even better! Thinking of you.
There are alternative drugs but nothing natural that will do the job intended for Tamoxifen or the Aromatase Inhibitors. You should discuss this with your Oncologist taking into consideration your bone health. As always the benefit should be weighed against the risks in each individual case. Regards ......
