Thank you for confirming that is the study. I've been on letrozole about 6 weeks, so a bit longer than you. Have noticed the arthritis in my thumbs is a bit worse but I can still use them. My hair, lost during chemo, is taking its sweet time to grow and the letrozole and/or chemo could be responsible.

Assume you can have serious side effects immediately, down the road at any time, or not at all. But in case things do change for the worse, it's good to have that study in my back pocket for reference.
