The rates of triple-negative breast cancer (TNBC) among women in the United States varies substantially by race and geographic location, according to a new study of more than 133,000 women diagnosed with TNBC from 2015 through 2019.
The analysis found that overall Black women were twice as likely as White women to be diagnosed with TNBC. For both Black and White women, the rates were highest in Iowa, Mississippi, and West Virginia. But for Black women in Delaware, Missouri, Louisiana, and Mississippi, their rate of diagnosis was more than double what White women in those same states experienced.
The data suggests that social, environmental, and structural determinants of health are at play in shaping the geographically patterned risk of TNBC, Hyuna Sung, PhD (above) senior principal scientist at the American Cancer Society and her colleagues concluded.
