Obesity-Related Cancer Deaths are on the Rise and Trends Parallel Those Observed for Heart Disease.

While Overall mortality rates for cancer continue to decline in the U.S., since 2011, that decline has slowed for obesity-associated cancers.  The mortality trends for obesity-associated cancers mirror those for heart disease,

According to Christy Avery, PhD, of the University of North Carolina at Chapel Hill, and colleagues . “After four decades of decline, annual improvements in heart disease mortality slowed in 2011; this slowing has been associated with the obesity epidemic,”   [Avery CL, Howard AG, Nichols HB, JAMA Open. 2021;4(5):e218356. doi:10.1001/jamanetworkopen.2021.8356].  

The researchers found that trends in obesity-associated cancer mortality and heart disease mortality showed slowing improvements that emerged in the second decade of the 21st century.  The investigators conclude these effects are caused by the ongoing obesity epidemic in which 2 out of 5 Americans are now obese.
