Which of the following is a risk-reducing behavior for breast cancer?

Smoking cessation is recognized as a risk-reducing behavior for breast cancer due to the association between smoking and various types of cancer. Research indicates that tobacco use can have a detrimental effect on overall health and is linked to an increased risk of breast cancer, among other malignancies. By quitting smoking, individuals can substantially lower their risk not only for breast cancer but can also improve their overall health, which is crucial when considering cancer prevention strategies.

The other behaviors listed have been associated with increased cancer risks. For example, increased alcohol consumption is linked to a higher risk of breast cancer, as excessive alcohol intake has been shown to affect hormone levels and increase cell proliferation in breast tissue. Similarly, a high-fat diet and decreased physical activity have both been associated with a rise in obesity, which is a known risk factor for developing breast cancer. Maintaining a healthy weight through balanced nutrition and regular physical activity is essential for reducing cancer risk.
