Help remove excess estrogen from circulation

White button mushrooms, such as crimini, commonly found in grocery stores and salad bars, help remove excess estrogen from circulation, making them helpful for preventing breast cancer. A tissue culture study published in the November 2010 issue of the journal Experimental Biology and Medicine found that white button mushrooms, along with four other varieties of common and specialty mushrooms, significantly suppressed breast cancer cell growth and reproduction. However, further studies are needed to confirm these preliminary results.
