Hello @stephied welcome to connect. I also had an oopherectomy, and extended endocrine therapy. It is not easy, and good for you for getting this far. That being said, you should have an honest conversation about the fatigue with your doctor. I have learned that sometimes, the things we attribute to these drugs are in fact something else entirely.
I don’t know your age or other health history, but I was in my 30s when I started, I have come to understand that endocrine therapy accelerated the aging process considerably. So the issues an 80 year old woman might have, I started having in my 50s. The good news is that I made it to 60 and certainly would not have done without the treatments.
When I started having fatigue issues, my doctor initially tested my thyroid and said it was a little off so a little thyroid pill helped a ton. I can’t say what yours might be, but quality of life is important.
Are you comfortable talking to your doctor about this? Have you remained cancer free since 2016?
