Physical activities, such as walking and cycling, could decrease the risk of breast cancer diagnosis in middle-aged women, according to a new study.
Women who completed a few hours of physical activity each week were shown to be less likely to be diagnosed with breast cancer after menopause when compared to more sedentary women, concludes a study published in Cancer Epidemiology, Biomarkers & Prevention.
Breast cancer risk decreased by 40% for women who became active after menopause and those who exercised regularly throughout their life had a decreased risk of 42% compared to those who didn’t.
The study followed 59,308 postmenopausal women over a twelve year period and through a series of questionnaires found that high levels of recent physical activity were associated with a 10% decrease in risk for breast cancer.
Many previous studies have been done on the subject leading researchers to believe some of the most important factors in predicting breast cancer risk include both activity levels after menopause as well as whether or not women were active earlier in life. Other related factors were considered such as immune response as well as weight control.
