Breast cancer is the most commonly diagnosed cancer among black women, and an estimated 30,700 new cases are expected to be diagnosed in 2016. Similar to the pattern among white women, breast cancer incidence rates among black women increased rapidly during much of the 1980s , largely due to increased detection by mammography screening. However, while rates thereafter generally stabilized in white women they continued to increase, albeit more slowly, in black women (0.5% per year from 1986 to 2012).4 As a result, incidence rates in black and white women converged in 2012.  The continued increase in incidence rates in black women may in part reflect the rising prevalence of obesity in this group (Figure 9).
During 2008-2012, the overall breast cancer incidence rate in black women was 124.3 cases per 100,000 women, 3% lower than in white women (128.1). However, rates were higher in black than in white women in seven US states (Alabama, Kentucky, Louisiana, Mississippi, Missou…
