@angele2times Estrogen is continued to be produced in females after menopause by the fat in their body. That is one reason they talk about taking off excess weight. I found that impossible as Arimidex caused me to gain twenty-five pounds over the five years on was on it and NOTHING I did would make a single pound leave. NOTHING! I had never been overweight in my life until I had to take Arimidex. I recently read that selenium degrades estrogen, and I am taking it now.
