Adolescent Diet and Breast Cancer Risk

Abstract

Although breast cancer risk increases with age, the importance of early events on breast cancer development is increasingly recognized. Compared to the plethora of studies on adult dietary exposures and breast cancer risk, the field of adolescent diet and breast cancer risk is still in its infancy. We review the data on breast cancer risk and diet during adolescence (defined as between ages 11 and 19) with a focus on the dietary exposures that have been investigated most in adult diet. The current literature suggests possible associations with dietary intake of soy and red meat and breast cancer risk. However, the lack of strong associations for other exposures may be due to methodological issues regarding precise measurement and a paucity of published studies. Overall, the area of early life exposures and cancer risk deserves more research and increased resources to advance the field.
