Maps of clusters of states with the highest in-situ female breast cancer rates in the USA
Below are maps of clusters of states with the highest in-situ female breast cancer rates in the USA. The clusters were found by counting the number of shared borders among states with the highest in-situ breast cancer incidence rates of white, black, and Hispanic women.
Included are also the lists of states with the highest in-situ female breast cancer rates.
