Chowing down on cruciferous veggies reduces the risk of recurring breast cancer, say Vanderbilt University researchers, while consuming too many high-fat dairy products produces an opposite effect, according to the National Cancer Institute (NCI). The paper on veggies presented at the American Association for Cancer Research showed that the more cruciferous vegetables a woman ate in the first two years after her breast cancer diagnosis, the lower was her risk of the cancer returning or death from the original cancer. Eating broccoli, cauliflower, bok choy and cabbage worked to reduce the rate of recurring breast cancer by 35 percent and the risk of death in the following nine years by 62 percent.

On the other side of the coin, the NCI study showed that women treated for early stage breast cancer that regularly ate one or more servings of high-fat milk, cheese, yogurt or ice cream increased their risk of dying of breast cancer by 44 percent and of earlier death from all causes by 64 percent.
