I'm certifiably "normal"

Well, when it comes to the results of the CYP2D6 test, I'm normal, anyway. What’s a CYP2D6 test? you may ask. It just so happens that I’m quite knowledgeable about it now. If you will recall, my oncologist wrote a prescription for the drug, Tamoxifen, for me to start taking for the next few years. Tamoxifen is a widely-prescribed drug for women who have been treated for hormone-receptor-positive breast cancer (like me).
