Study links teen physical activity to lower breast cancer risk
A new study found that teenage girls who do at least two hours of fun physical activities like sports or dancing each week may have a lower chance of getting breast cancer when they grow up.
The researchers looked at breast tissue and stress levels in these girls and found that those who were more active had less dense breast tissue and lower stress levels.
This is important because dense breast tissue is linked to a higher risk of breast cancer.
The study also found that many teenage girls aren't doing enough physical activity, which is a concern because breast cancer rates are going up in young women.
The researchers say more studies are needed to understand how this affects breast cancer risk in the long term.
Adolescent girls with at least 2 hours of recreational physical activity per week showed lower breast density and stress biomarkers.
The study was conducted by researchers at Columbia University Mailman School of Public Health.
Findings were published in the journal Breast Cancer Research.
More than half of the participants reported no recreational physical activity in the past week.
The study suggests a potential link between adolescent physical activity and reduced breast cancer risk later in life.
