New Link Between Diet and Cancer

Breast cancer patients who follow a low-fat diet may reduce the chance that their tumors will return, according to new research unveiled at this week's meeting of American Society of Clinical Oncology. The study showed that women who followed a low-fat diet had more than a 20 percent reduction in their rate of recurrence over five years. It's still unclear if the benefit stems from the reduced amount of fat that these women consumed or their consequential weight loss. Another factor could be the foods that these women chose to substitute for the fat in their diet -- possibly more fruits and vegetables. In any case, researchers agree that this is the first time that a large, rigorous study has shown the impact of diet on any cancer.
