@windyshores what is an undetectable level? No one had a baseline of my estrogen level. My oncologist when asked how they knew it was working he stated ‘we take it for granted’. When I had him order up an estrogen test it came back ‘<10’. How number do you get as undetectable or does the report say ‘undetectable’? I’m still following up on my estrogen levels but not getting very far. Is there a specific test I should be asking for. My oncologist and primary care doctors don’t seem interested. 🤷🏼‍♀️
