Look into the populus who were raised in Morenci AZ in the 60's, 70's and 80's .
There have been a multitude of my former classmates who either died young and still lived in Morenci or who have moved away and have passed from some form of cancer or are currently suffering, or are survivors of this disease. There has to be a correlation to this. There are too many occurences. Either caused by the copper mines air quality at that time or the occurrence of radiation fall out in that area.
