More Americans blame cancer on things like food additives, stress and beef hormones than on diet and other everyday steps people can take to lower risk, according to an AICR survey released today, on World Cancer Day.
The 2015 AICR Cancer Risk Awareness Survey shows that few Americans realize that factors like alcohol, obesity, lack of physical activity and poor diets have been shown to increase cancer risk. Instead, Americans continue to worry about factors over which they have either little or no control (genes, for example) or for which the link to cancer remains unclear (food additives).
The AICR Cancer Risk Awareness Survey The survey has been run periodically since 2001 and asks respondents to select those factors they believe have “a significant effect on whether or not the average person develops cancer.”
The survey gives experts a sense of whether Americans are focusing on the factors that make a proven difference in cancer risk, and today, that news is decidedly mixed:
The factors that Americans are focusing on represent a mix of legitimate risks (94 percent correctly identified tobacco use; 84 percent cited excessive exposure to the sun) and risks for which research has yet to provide definitive answers (food additives: 62 percent; genetically modified foods: 56 percent; stress: 55 percent; hormones in beef: 54 percent).
"When it comes to cancer, there are no guarantees," she said. "But the science on lowering cancer risk has never been clearer. Thousands of studies have been analyzed by AICR in our Continuous Update Project reports – the largest ongoing analysis of cancer prevention research in the world. These studies show that a healthy diet, regular activity and healthy weight could cut cancer incidence by one-third.
AICR estimates that about 340,000 US cancer cases could be prevented through changes in diet, weight, and physical activity.
