PHILADELPHIA (WPVI) --Eating foods with soy may help some women battling breast cancer.
Researchers followed more than 6,000 patients for nine years to analyze their intake of isoflavone, a compound in soy products.
Women who ate the most soy were 21 percent less likely to die than women who ate the least.
It may be that soy has a protective effect. but this was only seen in women whose cancer is negative for hormone receptors.
