Exercise Slashes Breast Cancer Risk: Columbia Study Reveals Key Benefits for Teens

• Research from Columbia University Mailman School of Public Health indicates that regular exercise in adolescence significantly reduces the risk of breast cancer.
• Adolescent girls who engage in sports and recreational exercise protect themselves from future breast cancer, impacting breast tissue structure and stress biomarkers.
• Exercising for at least two hours a week leads to positive changes, including reduced water content and density in breast tissue, both linked to lower cancer risk.
• Girls who exercised regularly also showed lower stress levels, as measured by urinary biomarkers.
• The study, published in 'Breast Cancer Research', emphasizes the critical role of physical activity in combating rising breast cancer rates among young women.

Why It Matters: Regular exercise during adolescence significantly lowers breast cancer risk by positively altering breast tissue and stress levels.
