Breast cancer prevention starts with healthy habits — such as limiting alcohol and staying physically active. Understand what you can do to reduce your breast cancer risk.
If you’re concerned about breast cancer, you might be wondering if there are steps you can take toward breast cancer prevention. Some risk factors, such as family history, can’t be changed. However, there are lifestyle changes you can make to lower your risk.
What can I do to reduce my risk of breast cancer?
Lifestyle changes have been shown in studies to decrease breast cancer risk even in high-risk women. The following are steps you can take to lower your risk:
• Limit alcohol. The more alcohol you drink, the greater your risk of developing breast cancer. The general recommendation based on research on the effect of alcohol on breast cancer risk is to limit yourself to less than 1 drink per day as even small amounts increase risk.
• Don’t smoke. Accumulating evidence suggests a link between smoking and breast cancer risk, particularly in premenopausal women. In addition, not smoking is one of the best things you can do for your overall health.
• Control your weight. Being overweight or obese increases the risk of breast cancer. This is especially true if obesity occurs later in life, particularly after menopause.
• Be physically active. Physical activity can help you maintain a healthy weight, which, in turn, helps prevent breast cancer. For most healthy adults, the Department of Health and Human Services recommends at least 150 minutes a week of moderate aerobic activity or 75 minutes of vigorous aerobic activity weekly, plus strength training, at least twice a week.
• Breast-feed. Breast-feeding might play a role in breast cancer prevention. The longer you breast-feed, the greater the protective effect.
• Avoid exposure to radiation and environmental pollution. Medical-imaging methods, such as computerized tomography, use high doses of radiation. While more studies are needed, some research suggests a link between breast cancer and radiation exposure. Reduce your exposure by having such tests only when absolutely necessary.
