A recent study shows that while most women are aware of lifestyle factors that increase the risk of breast cancer, few take steps to reduce those risks. The findings, published in a 2026 survey, highlight a surprising gap between knowledge and action. Despite understanding that lifestyle choices can influence breast cancer risk, many women do not modify their habits. Researchers say that up to 30 percent of breast cancer cases could be prevented through regular physical activity, maintaining a healthy weight, limiting alcohol consumption, and breastfeeding. The study, conducted by the American Cancer Society, involved around 33,000 American women participating in the Cancer Prevention Study-3, a long-term program focused on cancer prevention. The results showed that 91 percent of the women knew that a lack of exercise increases breast cancer risk, but only 27 percent met the recommended levels of physical activity per week. These levels include 150 to 300 minutes of moderate activity or 75 to 150 minutes of vigorous activity each week. Dr. Alpa V. Patel from the American Cancer Society emphasized that raising awareness alone is not enough. "We need to understand whether this awareness translates into actions and how we can help women close the gap," she said. The study also found a significant gap related to alcohol consumption. While 85 percent of women know that drinking alcohol increases breast cancer risk, 69 percent still report consuming alcohol regularly. The findings suggest that while public awareness of breast cancer risk factors is high, translating that knowledge into behavior change remains a challenge. Researchers believe that targeted interventions and support are needed to help women make healthier lifestyle choices. The study underscores the importance of not only informing the public but also providing practical tools and resources to help individuals implement these changes effectively.
