Maps of clusters of states with the highest laryngeal cancer rates in the USA

Below are maps of clusters of states with the highest laryngeal cancer rates in the USA. The clusters were found by counting the number of shared borders among states with the highest laryngeal cancer incidence and mortality rates for every combination of gender and race/ethnicity.

Included are also the lists of states with the highest laryngeal cancer rates.
