UV intensity is not the most important factor in skin cancer fatalities. While residents of Colorado have always been subjected to the highest UV intensities in the United States, Colorado has one of the lowest skin cancer fatality rates of all the states. In contrast, New England, which has much lower UV intensities, has a death rate from skin cancer 25% higher than it is in Colorado. In addition, although equatorial regions have higher UV intensities, the lowest reported skin cancer deathrates in the world come from Mauritius and Nicaragua, two equatorial countries. On the other hand, Ireland has the world’s third highest rate. Evidence is strong that UV intensity is not the principal factor in determining the skin cancer death rate. Genetic factors, skin pigmentation, behavioural characteristics, medical facilities, broad straw hats, and sun screen lotion all have some influence on skin cancer fatalities.
