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.
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
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.
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
Working as a dietitian specializing in weight loss for the past two years, my patients consistently report similar challenges. Lifestyle changes are hard – going from daily take out/fast food to home-cooked meals, for example, requires a dramatic change in your daily routine. Suddenly you have to not only plan out a grocery list, but you might also have to develop cooking skills and allow extra time in your day for food preparation.
One major thing I’ve learned in helping people manage their weight is that anyone can make a lifestyle change, but the motivation and commitment comes from you.
Most people are aware that maintaining a healthy body weight leads to health benefits (from reducing risk of cancer, to diabetes, to increasing life span and improving quality of life). Your doctor, a friend, or a significant other may have put pressure on you to lose weight. However, at the end of the day, the one thing that really matters is your own desire and motivation to make that change.
I like to show my patients a model called the Stages of Change Transtheoretical Model, developed by a health psychologist at the University of Rhode Island and his colleagues. This model depicts 5 stages and can be a helpful tool for anyone interested in embarking in the life-long commitment that is necessary to lose and maintain weight loss. Here are the stages: Continue reading
