Study: Vast majority of cancers caused by lifestyle, not “bad luck”

By Posted on 3 Comments on Study: Vast majority of cancers caused by lifestyle, not “bad luck”

Bad diet, inactivity, smoking and drinking alcohol – all are among the causes of up to 90 percent of cancers, according to a new analysis that stresses how many cases of cancer are under our control.

This paper, published in Nature, is in stark opposition to the paper out earlier this year. Published in Science, that paper found that the majority of cancer cases were caused by “bad luck,” our cells going awry without much people could do to control them. At that time, we pointed out some key flaws with their analysis.

This study used the same premise and a lot of the same data as the Science article to reach a different conclusion: lifestyle makes a difference when it comes to cancer risk.

Here at AICR, where we focus on how diet, physical activity and body fat link to cancer, a wide and consistent body of evidence shows that these factors make a difference. One third of the most common cancers can be prevented with diet, staying lean, and being active.

    How can bariatric surgery and a mom’s smartphone link to reduced cancer risk?

    These studies were among the winners of the AICR research poster competition, announced yesterday at the annual Obesity Week conference. Obesity is associated with increased risk of a number of cancers, including ovarian, endometrial, and colorectal. The winners, awarded support by AICR, included three early investigators and two student prizes.

    In no particular order, here are highlights of this year’s winners for outstanding posters. Congratulations to all. Note: these poster findings are not yet published and have not yet gone through the peer-reviewed process.

    Ǻsa Anveden, MD PhD University of Gothenburg, Sweden

    AvendenBariatric surgery is one obesity-treatment option and previous research suggests decreased risk of cancer following surgery. This surgery may reduce the risk of cancer in obese women, suggests the finding of this study.

    Anveden and her team followed over 4,000 obese people (70% women) for up to 26 years to look for cancer incidence. About half the participants had undergone bariatric surgery, and they were matched to a group of obese controls who received usual care.

      Tasty Swaps to Help You Eat Less Red and Processed Meats

      By Posted on 2 Comments on Tasty Swaps to Help You Eat Less Red and Processed Meats

      By now you’ve probably heard about the report last week categorizing hot dogs, bacon and other processed meats as a cause of colorectal cancer, and probably red meats also. In general, that supports AICR’s longstanding and continuous analysis of the research.

      Since 2007, AICR has recommended to avoid processed meat and eat no more than 18 ounces of (cooked) red meat weekly to lower cancer risk. If you’re used to eating red meat or that daily salami sandwich, shifting your diet may seem daunting.

      Here are swap suggestions to help. For the recipes, visit our updated Healthy Recipes.
