One thing that might be interesting to research is
3,3'-Diindolylmethane aka DIM. Some people are taking it to reduce estrogen. I don't know if it doesn though make body builders are using it to prevent testosterone from converting to estrogen to lose 'man books'. But I looked at a handful of studies suggesting it has strong anti-tumor properties for breast cancer cells. Since it's mostly found in cruciferous vegetables that are also mineral-rich, I'm doubling them in my diet. (A few of the studies noted that the vegetables are more powerful raw than cooked. I think broccoli smoothies are palatable when made with fresh apple and some ginger simple syrup. But I can drink vegetables that I otherwise wouldn't like to eat so smoothies are my
friends in getting more fresh vegetables into diet.)

I see Dr. Stacy D'Andre in Integrative Medicine, and she is wonderful!! Highly recommend her. My medical oncologist was Dr. Minetta Liu, but she left Mayo, so I no longer have a med onc doc. Need to figure that out.
