Breast cancer is the most commonly occurring cancer in women and the lifetime risk (at age 85) of being diagnosed is approximately 1 in 10 [1], the highest probability out of all cancers. Breast cancer screening programs have been shown to decrease the mortality rates of women age 50-69 [2] due to detecting cancer at an earlier, treatable stage, however compliance is low due to a variety of reasons. While the understanding of the underlying causes and mechanisms leading to breast cancer is increasing, development of the disease is not fully understood. Hence, there has been a push to propose, develop and understand risk factors for the disease; which are defined as those characteristics that people with the disease have in common [3].
