so sorry to hear of your recurrance. Keep a positive attitde. you beat this once you can do it again. About the estrogen, when you had your hysterectomy were both overies removed. They are not always. Also, estrogen is produce in fat cells. Even men can have high levels of estrogen if they are overweight. I am at risk becouse I a very overweight. That is why my Dr and I have created a plan to bring my BMI down in the next 8 months.
Hope things go well for you.
