Limiting carbs could reduce breast cancer recurrence in women with positive IGF1 receptor

Reducing carbohydrate intake could reduce the risk of breast cancer recurrence among women whose tumor tissue is positive for the IGF-1 receptor, researchers report. Using an unusual approach, this study assessed the combined association of two factors implicated in tumor growth -- carbohydrate intake and IGF1 receptor status -- to test whether activating the insulin/insulin-like growth-factor axis can impact breast cancer.
