Replying to whr : “ I had the oncologist check my hormone levels when I recently had blood work done and they are quite low, but since there wasn't a benchmark taken before I started the medication, not sure what that exactly means but will have it checked again in October.”

whr, I totally agree with your statement and I am exactly where you are right now. I asked my oncologist how did he know Anastrazole was working for me & he told me they take it for granted. He had to see IF there was even a test for estrogen levels. 🤷🏼‍♀️ I did the blood test. It was <10. No specific number and no benchmark prior to starting med. I had to call office for results and the said <10 is good. That’s not good enough fir me since I didnt have baseline number. Anyway, I’ve taken n this myself. I’m working with a hormone PA and did a saliva test after being off med for 1 month. I will perform this test again in 2-3 months since I started up the anastrazole again. During the month off I didn’t really notice too much difference in hip pain, but just overall feeling was better.
I did not get or ever been talked about Oncotype number. And my Oncologist never has said I should take osteoporosis med. I’ve been on for 1 yr 11 month and my 2021 bone density shows osteoporosis now vs osteopenia, but no recommendation on med. I had a mastectomy one side , no lymph node involvement and no radiation or chemo.
Best of luck 💜
