Which lifestyle factor is directly linked to an increased risk of breast cancer in women?

• A. High vegetable intake
• B. Sedentary lifestyle
• C. Frequent dieting
• D. Consuming low-fat diets

Answer: (B)

A sedentary lifestyle is directly linked to an increased risk of breast cancer in women due to its impact on body weight and overall health. Physical inactivity can contribute to obesity, which is a known risk factor for various cancers, including breast cancer. Regular physical activity is associated with maintaining a healthy weight and can help regulate various hormones, such as estrogen and insulin, which may be involved in breast cancer development. In contrast, a high vegetable intake, frequent dieting, and low-fat diets, while important for overall health, do not have a direct causal relationship with increased breast cancer risk. In fact, a diet rich in vegetables is generally considered protective due to the presence of antioxidants and other beneficial nutrients. Frequent dieting can indicate an unhealthy relationship with food but does not inherently increase breast cancer risk like a lack of physical activity does. Low-fat diets can be part of a healthy lifestyle, but they are not directly tied to breast cancer risk in the same way physical inactivity is. Therefore, understanding the benefits of maintaining an active lifestyle is crucial in reducing the risk of breast cancer.
