3 strategies that can lower breast cancer risk
Maintaining a commitment to a physically active lifestyle throughout life can help women lower their risk for breast cancer.
Breast cancer affects millions of individuals each year. The World Cancer Research Fund International reports that breast cancer is the most commonly diagnosed cancer in women across the globe, affecting roughly 2.3 million women each year.
Despite the global prevalence of breast cancer, various organizations report high five-year survival rates, particularly among women whose cancers are detected in the earliest stages of the disease. In fact, a 2023 study published in the journal BMJ found that the risk for dying from breast cancer in the five years after an early- stage diagnosis fell to 5 percent in recent years, a notable improvement from the 14 percent risk of death that was reported in the 1990s.
Increased survival rates for breast cancer are welcome news for women and their families. The higher survival rates are a byproduct of the tireless efforts of cancer researchers, who also have discovered links between the disease and certain lifestyle factors. Though there's no way to eliminate one's risk for breast cancer entirely, the American Cancer Society notes certain variables are within women's control. With that in mind, women can consider these three strategies that can lead to improved overall health and might help women lower their risk for breast cancer as well.
1. Reach and maintain a healthy weight. The benefits of maintaining a healthy weight include a lower risk for heart disease and stroke, and women should know that weight and breast cancer risk are linked as well. According to the ACS, increased body weight and weight gain as an adult are linked to a higher risk of developing breast cancer. That's particularly so among postm eno-pausal women. A 2023 study published in the journal BMC Women's Health found that the chances of developing breast cancer increase among postmenopausal women who are obese.
2. Avoid a sedentary lifestyle. Exercise is one of the ways to achieve and maintain a healthy weight, so it makes sense that being physically active can reduce breast cancer risk. The National Cancer Institute reports that a 2016 meta-analysis of 38 cohort studies found that the most physically active women had between a 12 and 21 percent lower risk for breast cancer than women who were the least physically active. The NCI also notes that additional studies have found that women who become more physically active after menopause also have a lower risk for breast cancer than those who do not.
3. Limit or eliminate alcohol consumption. The ACS urges women who drink to consume no more than one alcoholic drink per day, noting that consumption of even small amounts of alcohol have been linked to an increased risk for breast cancer. Officials with the MD Anderson Cancer Center note that the link between alcohol consumption and breast cancer risk is low. However, the MDACC notes that alcohol can contribute to unwanted weight gain, thus increasing cancer risk. In addition, alcohol can increase levels of estrogen and other hormones associated with breast cancer.
It may be impossible to completely prevent breast cancer. However, women can embrace strategies that improve their overall health in ways that lower their risk for breast cancer.
