31 Days, 31 Things You Didn't Know About Breast Cancer

High socioeconomic status (usually defined by a high income and/or high education level) has been associated with an increased risk of breast cancer. The reason for this relates to differences in risk factors seen in women of different education and income levels. For example, compared to women of lower socioeconomic status, women of higher socioeconomic status tend to have their first child at a later age, have fewer children and breastfeed for less time, all of which are known to increase the risk of breast cancer.
