@flowergal - Thanks for the information. Yes, he is right: Estrogen IS a helpful hormone for the brain and bones, even in males. However, there are certain situations when estrogen and progesterone are not appropriate. One of these is having a cancer that shows it is receptive to these hormones - As it is in your, mine, and many others. That means our type of cancer uses estrogen to grow and develop.

In your case, 15% is pretty low; some doctors will argue that the level is so low that it is not worth stopping HRT and possibly cause issues with the bones and brain. Your endocrinologist is one of them. However, you have a grade 3 type of cancer. This means it is a faster-growing cancer and more likely to spread. Oncologists are less apt to take any chances when the cancer grade is 2-3. Have you discussed this in-depth with your oncologist?

Did you have radiation? In my decision-making, I used PreludeDX.

"DCISionRT is a risk assessment test for patients with ductal carcinoma in situ (DCIS). The test was developed by PreludeDx and built on research that began with funding from the National Cancer Institute to better understand the biology of DCIS. DCISionRT assesses a patient’s individual biology along with other risk factors to provide a personalized assessment that predicts the risk of your DCIS coming back (recurring) over the next 10 years. The test calculates a personalized recurrence score and identifies your risk as low or elevated. DCISionRT provides information that may help you and your physician make a more informed treatment decision. "

My insurance covered it, so I didn't pay for it. Based on the results shown, my oncologists recommended Radiation and Aromatase Inhibitors. I decided to get the radiation; however, I chose not to take AIs.
