To help journalists tease out that risk, Robien pointed to several key resources:

  • The World Cancer Research Fund International’s breakdown of cancers linked with greater body fat. The chart shows the increase in cancer risk, by type of cancer, as weight goes up.
  • The same group’s cancer preventability estimates, which detail the percentage of cancers that could be prevented if people were, on average, at their appropriate body weight. For the U.S., the figure for preventable cancers was 21 percent.
  • A pivotal report from 2012 by the Institute of Medicine that details the role of obesity in cancer survival; research suggests obesity can influence cancer survival and recurrence.
