In the breast, when too much estrogen reaches these receptors, the risk of cancerous growth rises. Both raloxifene and tamoxifen block estrogen when it gets to the receptor. Remarkably, so do several kinds of foods. But the wonderful thing about foods is that they can block the effect of estrogen in many different ways. That gives you a greater chance to lower the risk of cancer while avoiding the toxicity that could come with drugs.
Foods can change the actual composition of the breast and make breasts more resistant to cancer.
And, in some cases, foods actually can reduce the size of an existing tumor. Buy whole flaxseeds, grind them and blend them into orange juice, yogurt, salads, etc. Chinese women, who eat far more soy than American women, have 80 percent less breast cancer. And flaxseed is so potent that researchers now use it to shrink tumors between diagnosis and surgery. The recommended doses are 35-60 grams of soy or 25 grams of flaxseed a day.
