Cancer death rates vary nearly two-fold when mapped by U.S. congressional district, with rates generally lowest in Mountain states and highest in Appalachia and areas of the South, according to a new analysis by American Cancer Society researchers.

Many adults in the U.S. are not getting the recommended screening tests for colorectal, breast and cervical cancers, according to data published in the Centers for Disease Control and Prevention’s (CDC) Morbidity and Mortality Weekly Report. For 2013, screening for these types of cancers either fell behind previous rates or showed no improvement.

In time for the start of grilling season, experts at the American Institute for Cancer Research (AICR), an organization that studies the impact of lifestyle on cancer risk, issued a warning about the hidden health hazards of cookouts and campfires. "Research now shows that diets high in red and processed meat increase risk for colon cancer," said AICR registered dietitian Alice Bender.
