Research already shows that physical activity reduces the risk of postmenopausal breast cancer. Now a new study attempting to better understand this link has found that walking for an hour a day reduces a woman’s risk, regardless of your weight, estrogen use or other factors linked with increased risk.
The study was published in Cancer Epidemiology, Biomarkers & Prevention.
As previous research has shown, this study found that more activity offers more protection for postmenopausal breast cancer.
For the study, researchers gathered data from almost 74,000 women who were ages 50 to 74 when they enrolled 19 to 20 years ago. At the start, the women answered questions about their activity habits, weight, hormone use and other risk factors. They updated the information periodically until the study ended in 2009. By that time, 4,760 women were diagnosed with breast cancer.
Almost one of every ten women reported they were not active at all. Almost half said walking was their only recreational activity. Continue reading
You may know that being a healthy weight and exercising can cut your risk of breast cancer, but understanding how to translate these recommendations into action is one of the “critical gaps” in research that can save lives, finds a new study published in Breast Cancer Research.
The study, which comes at the start of Breast Cancer Awareness month, identifies ten critical gaps in breast cancer research. The authors include more than 100 experts.
Developing interventions and support to improve breast cancer survivors’ health and well-being is another gap in the research. Other critical areas where more research is needed include genetics, molecular markers, treatment and tailored screening and survivorship materials. Convincing clinicians to shift their practice into prevention is another area that needs work, according to the study.
You can read all ten gaps the authors identify in the paper.
As the study points out, when it comes to lifestyle change for breast cancer prevention, there remain many unknowns. We don’t know the relative affect of lifestyle changes on lowering the risk of different types of breast cancers, such as ER negative or ER positive. Does the effect of eating habits depend upon whether you are 15 years old or 50? And how many years do these lifestyle interventions offer protection? Continue reading
