A new study by scientists at the German Cancer Research Center has identified avoidable breast cancer risk factors.
The research team, led by Karen Steindorf and Jenny Chang-Claude, has been searching for risk factors that can be influenced by changes in lifestyle and behavior.
They focused on aspects such as taking hormones for relief of menopausal symptoms (hormone replacement therapy), physical activity, overweight and alcohol consumption. All these lifestyle factors have been identified in prior studies as possible risk factors for the development of breast cancer.
Of the modifiable lifestyle factors, it is primarily hormone replacement therapy and a lack of physical activity that increase a woman`s risk of developing breast cancer.
Alcohol consumption and overweight were found to have less influence on breast cancer risk.
