Which factor is associated with an increased risk of breast cancer?

Low physical activity is associated with an increased risk of breast cancer. Numerous studies have demonstrated that a sedentary lifestyle can contribute to various health issues, including obesity and metabolic syndrome, which are linked to a higher likelihood of developing breast cancer. Physical activity is thought to help maintain a healthy weight, regulate hormones like estrogen, and improve immune function, all of which may play a role in reducing cancer risk.

While factors such as high calcium intake, high carbohydrate diets, and high fruit consumption are components of dietary intake and can influence overall health, they do not have the same direct association with increased breast cancer risk as low physical activity does. Regular exercise and physical activity are key components in cancer prevention strategies, highlighting the importance of an active lifestyle in reducing the risk of various forms of cancer, including breast cancer.
