Hi,
You might ask your onc about the CYP2D6 tamoxifen test. It's a test to see if you have high or low CYP2D6 (if the liver can metabolize tamoxifen). Only 10% of people do not. I was among the 10% of poor metabolizers. This test is still controversial, some thinking maybe other factors contribute to metabolic rate of liver. You can read the research. If you don't metabolize tamoxifen some doctors say you won't experience symptoms such as hot flashes. SO hot flashes are good. I felt wonderful on tamoxifen, no hot flashes at all, so maybe I didn't metabolize it well. Who knows?? BUT if I could have taken tamoxifen I would have. It builds bones instead of tearing them down like the AI's. Women on tamoxifen also have the option, after 3-5 years on tamoxifen, of taking an AI another 3-5yrs. Wishing you the best!!
