There is another interesting fact about breast cancer. It is one of the cancers whose incidence changes dramatically when people migrate and change their dietary habits. Asian women - those from Japan and China are known to have a very low incidence of breast cancer. This is generally attributed to their much higher levels of consumption of soy, seafood and tea. When they move from their native countries to America they acquire the high American levels of breast cancer occurrence within one generation itself. It is believed that when Asian women move to America they consume high levels of animal fat and low levels of soy, seafood and tea. 

Protection from breast cancer is the foremost benefit promised and indeed delivered by our good friend Soy.  There are many interesting studies that prove this point. A study found that Seventh Day Adventist women who are mainly vegetarians with high soya intake had a lower risk of breast cancer. An Italian study has found that high doses of genistein supplement (predominantly found in soy) showed an increased effectiveness in halting human breast cell proliferation.

My suggestion is that you start with soy right away. For starters you can begin with soy milk, tofu, miso (a form of soy paste) and tempeh (a fermented soy patty). Find a good soy cookbook. It is very easy to get used to the taste of soy. Most people who eat soy products even for a few days begin to really love it. Become the consumer of soy like Asians and decrease your cancer risks.
