For each Montanan receiving treatment in Montana for a diagnosis of breast cancer, a line from the Montanan’s residence to the city where the individual receives treatment is mapped and drawn. Most Montanans choose to receive treatment in six cities: Billings, Bozeman, Great Falls, Helena, Kalispell, and Missoula.
