I was taking tamoxifen after chemotherapy for about 1 year and now I'm on femara. I suffer from all those side effects and I'm wondering if I could stop taking femara ..bu t the problem is that I have not been taken it for 5 years what is recommended I think, but only for 4... does anybody know if I could stop taking it because if I add 1 year on tamoxifen and 4 on femara I have 5 years of therapy ... but I'm not sure what to do and my onkologist neither..
