Study: Almost Half a Million Cancers Worldwide Due to Obesity

Almost half a million cancer cases worldwide are due to the rising rates of overweight and obesity, making many of the most common cancers potentially avoidable, says a new study published in The Lancet Oncology.canstockphoto12101428

The study was funded in part by the World Cancer Research Fund (WCRF) International, which AICR is a member. AICR and WCRF now estimate that approximately 122,000 cases of cancers in the US are due to overweight and obesity.

Researchers in The Lancet study calculated that  481,000 – 3.6% – of all new cancer cases in adults worldwide were attributable to high BMI in 2012, the latest global data available.

Obesity-related cancers are more likely to affect women than men, largely due to endometrial and post-menopausal breast cancers, according to the study. In men, excess weight was responsible for 1.9% or 136,000 new cancers in 2012, and in women it was 5.4% or 345,000 new cases. Continue reading


Preventing Prostate Cancer: The More We Learn, The Less We Know

The latest report from our Continuous Update Project (CUP), the process by which we rigorously review the global science linking diet, weight and physical activity to various cancers, focuses on the prevention of prostate cancer. We released it last night; this press release reviews the highlights, and takes you to the full report.obesity-cancer-infographic-prostate-x900

One new finding is that obesity is now recognized as a risk factor for advanced prostate cancer – the most deadly type.

Like all previous CUP Reports, Diet, Nutrition, Physical Activity and Prostate Cancer gives our expert panel the chance to review the research collected since the publication of our 2007 AICR/WCRF expert report, and to update their judgments about the strength of the evidence on specific links.

Which, this time at least, is just what they did. revealing how quickly the field of prostate cancer research has changed in just seven years.

Prostate Cancer Is Not One Disease – The panel’s judgments on specific links have changed because prostate cancer is now being studied differently than the way it was in 2007. Today, researchers know that not all prostate cancers are alike. Continue reading


Obesity Report: How Does Your State Rank?

Mississippi and West Virginia top the state rankings for adult obesity with Colorado again at the bottom, according to the new annual report on obesity that gives just a hint of positive news in another year of rising rates.

For cancer risk, the state of obesity is a major concern. Aside from not smoking, staying a healthy weight is the single biggest lifestyle factor related to cancer risk. AICR estimates that overweight and obesity increase risk of 8 cancer types.

The State of Obesity is the 11th annual report on obesity rates from the Trust for America’s Health and the Robert Wood Johnson Foundation. (The report was formerly called F as in Fat.) For each state, the report looks at obesity-related cancers as well as heart disease and other health disorders related to obesity. You can also see each state’s policies on issues related to obesity.

Overall, the news is not good: Every state in our country has over one in five people obese; in 43 states, the rates are one in four. Adult obesity rates increased in six states over the past year, and did not decrease in any. More than one in ten children become obese at ages 2 to 5. As of the last available data, 2011-2012, nearly one out of three children and teens are overweight or obese.

The report also found many disparities, with obesity rates highest in the South and among Blacks, Latinos and lower-income, less-educated Americans. A special report on disparities found that almost half of African Americans, 43 percent of Latinos, 33 percent of Whites and 11 percent of Asian Americans were obese.

Here’s the positive: After decades of rising obesity rates among adults, the rate of increase is beginning to slow, according to the report. And national childhood obesity rate has remained stable.

The report issues high-priority recommendations, such as focusing on healthy food financing and improving nutrition and activity in schools and child care settings.
