A respected oncologist said in an online YouTube, breast cancer prevention drugs should be "incredibly easy, very nontoxic, shouldn't interfere with your life, shouldn't make you worry about long-term toxicity, and be cheap." So before I start anti-estrogen therapy I am looking for an option that decreases the recurrences with the above qualities. The low-dose trials for tamoxifen (5mg for 3 years) sound promising because the toxicity and SE's are significantly lowered, but the recent trials have not included early stage no lymph node involved IDC. It is always a question of benefit vs risk, as well as adherence. I will discuss this with my oncologist.
