A study conducted by UNC researchers has found that any physical activity can reduce the risk for breast cancer. The study also found that weight gain can increase the risk.
Women who exercised more than 10 hours per week had the most significant reduction in risk for breast cancer, at 30 percent.
The study was led by Lauren McCullough, a doctoral candidate at the UNC Gillings School of Public Health. She and her colleagues studied more than 3,000 women from ages 20 to 98, about half of whom had breast cancer. The results were published in Cancer, a peer-reviewed journal of the American Cancer Society.
