For all the advances made in the United States in the “war on cancer” over the past 40-plus years, the battle against obesity-related cancer is another story. Case in point: a study(www.cdc.gov) published in Morbidity and Mortality Weekly Report last October. The authors of that study found that while the incidence of cancers not related to overweight and obesity decreased by 13 percent between 2005 and 2014, the incidence of overweight- and obesity-related cancers decreased by only 2 percent during the same period.
