More than a third of Idaho women over 40 did not receive important breast cancer screening in the last two years, reports the Idaho Department of Health and Welfare. That places Idaho last out of 50 states and the District of Columbia in cancer screening mammogram rates. The Cancer Data Registry of Idaho estimates there are over 122,000 Idaho women over the age of 40 who have not had a mammogram in the previous two years/Coeur d'Alene Press. More here.

Question: Any idea why Idaho would rank last for breast cancer screening?
