Women who have ever had  breast cancer might want to walk away from the brie, the butter  and the black cherry (and every other flavor) ice cream.

According to a study of 1,893 women, breast cancer survivors  who average as little as one serving per day of high-fat dairy  foods have a 49 percent higher risk of dying from breast cancer  than those who eat little or no high-fat dairy.

In absolute terms, breast cancer survivors who consumed the  most high-fat dairy had about a 12 percent risk of dying of the  disease.

The elevated mortality risk is therefore "modest," said lead  author Candyce Kroenke, a staff scientist at Kaiser Permanente,  the nonprofit healthcare provider. "But since it may not be so  difficult to lower your consumption of high-fat dairy, I think  if you have breast cancer it's worthwhile."
