									AICR’s Biennial Cancer Risk Awareness Survey Methodology: The AICR Cancer Risk Awareness Survey has been conducted every two years since 2001. Americans aged 18 and older are telephoned at random on behalf of AICR by International Communications Management (ICR) using the EXCEL omnibus service.      The first survey was conducted in May of 2001 and involved 750 Americans aged 18 and older who were telephoned at random. Margin of error: +/- 3 percent. The second survey was conducted in May of 2003 and involved 1,025 Americans aged 18 and older who were telephoned at random. Margin of error: +/- 2 percent. The third survey was conducted in May of 2005 and involved 1,010 Americans aged 18 and older who were telephoned at random. Margin of error: +/- 2 percent. The fourth survey was conducted in August of 2007 and involved 1,022 Americans aged 18 and older who were telephoned at random. Margin of error: +/- 2 percent. The most recent survey was conducted in August of 2009 and involved 1,021 Americans aged 18 and older who were telephoned at random. Margin of error +/- 2 percent.

Raw survey data tables – including breakdowns by sex, age, income, metro status and race, available upon request. For more detailed questions on survey methodology, contact John DeWolf at ICR: jdewolf@icrsurvey.com, (484) 840-4451.

Trend Holding steady. AICR’s Take Evidence regarding tobacco’s role in cancer risk is outside the scope of our Expert Report and was not judged by the expert panel. Other reports have convincingly linked tobacco to cancers of the mouth, pharynx, larynx, esophagus, lung, pancreas and bladder.

Trend Holding steady. AICR’s Take Evidence regarding the role of genetics in cancer risk is outside the scope of the Expert Report and was not judged by the expert panel. Other reports have estimated that only about five to ten percent of all cancers can be attributed to a genetic predisposition. The panel notes that individuals who do inherit BRCA1, APC, p53 or other “cancer genes” can significantly reduce their risk by making healthy changes to diet, level of physical activity, and weight.

Trend Rising; over 50% for the first time in the history of the survey. AICR’s Take Evidence linking the consumption of vegetables and fruits to lower risk was judged probable for the following cancers:  Colon  Pharynx  Rectum  Larynx  Lung  Esophagus  Stomach  Pancreas  Mouth Evidence of cancer-protection from vegetables and fruits was judged limited, but suggestive for cancers of the ovary and endometrium.

Trend Rising; over 50% for the first time in the history of the survey. AICR’s Take The strong link between obesity and cancer is one of the key findings of the AICR expert report. There is convincing evidence that excess body fat is a cause of the following cancers:     Colon Rectum Breast (Post-menopause) Endometrium    Pancreas Kidney Esophagus

The evidence that excess body fat is a cause of gallbladder cancer was judged probable. Limited, but suggestive evidence links excess body fat to liver cancer.

WHAT THE PANEL’S JUDGMENTS MEAN Convincing Evidence is strong, consistent and unlikely to change in the future Probable Evidence is compelling, with an overall consistency, but less strong than "convincing" Limited Evidence – Suggestive Evidence is too limited for a grade of "probable", but a general consistency in the data exists Limited Evidence – No Conclusion Too inconsistent or insufficient for a definitive grade

The evidence that alcohol is also a cause of liver cancer and a cause of colon and rectal cancer in women and was judged probable.

Trend Rising. AICR’s Take Physical activity seems to protect against cancer both directly (by helping to regulate the body’s hormone levels) and indirectly (by helping to prevent buildup of excess body fat, itself a convincing cause of several cancers.) There is convincing evidence that physical activity protects against colon cancer. Evidence linking physical activity to lower risk of post-menopausal breast cancer and endometrial cancer was judged probable. Limited, but suggestive evidence links physical activity to lower risk for premenopausal breast cancer, pancreatic cancer and lung cancer.

DIETS HIGH IN RED MEAT

Trend Rising slightly. The evidence is convincing that diets high in red meat are a cause of colon and rectal cancer. The evidence linking red meat to cancers of the esophagus, lung, endometrium and pancreas is limited, but suggestive.

Cancer: Most Feared, Least Understood Health Issue The AICR survey also revealed that Americans rate cancer as their #1 health concern. Thirty-seven percent of respondents named cancer their top concern compared to 21 percent who cited heart attack, 12 percent who cited diabetes and 8 percent who cited stroke.

But only 20 percent of respondents rated cancer a highly preventable disease, compared to for 34 percent for stroke, for 45 percent for heart attack and for 46 percent for diabetes.
