Teenage girls’ recreational physical activity linked to breast tissue composition, can impact cancer risk: Study
A new study has linked recreational physical activity in teenage girls with a lower water content in breasts, indicating a lower breast density, and lower levels of stress-related biomarkers.
Findings published in the journal Breast Cancer Research shed light on how physical activity during adolescence — a critical period for breast development — can impact biological pathways related to breast cancer risk in the future, researchers said.
“The importance and urgency of this research are underscored by the rising incidence of breast cancer in young women and the alarmingly low levels of recreational physical activity observed both in this study and among adolescents across the United States and globally,” first author Rebecca Kehm, assistant professor of epidemiology at the University of Columbia’s School of Public Health, said.
