We’ve just released our latest systematic review of the global literature linking diet, weight and physical activity to an individual cancer; this time, it’s stomach cancer in the spotlight, and there’s some striking news.
The report’s three major findings – that alcohol, processed meat and obesity increase the risk for stomach cancers – are entirely new. Much of the research makes important distinctions that previous research didn’t, and there’s more to know about stomach cancer risk than easily fits into a headline. Here, we answer questions about some of the nuances that have emerged.
Both here in the US and around the world, obesity rates continue to climb. Today, for the first time, more people are classified as obese than underweight, finds a major new study published in The Lancet.
The findings have severe implications for cancer rates. Aside from not smoking, staying a healthy weight is the single largest risk factor related to cancer risk. AICR research links excess body fat to ten cancers, including colorectal, postmenopausal breast and esophageal.
Here in the US, if everyone were a healthy weight, AICR estimates that approximately 128,000 cases of cancer could be prevented each year.
For postmenopausal women who are overweight, it makes sense that losing weight could reduce their risk of breast cancer because being overweight or obese increases the risk. But when overweight women are working to shed pounds, is it primarily exercise or cutting calories that makes more of a difference in lowering the risk?
Both, suggests a new study, with weight loss fueled primarily by exercise possibly leading to even more benefits – at least in the short-term for certain markers of breast cancer.
The study is one of the few randomized controlled trials that focuses on teasing apart the effect of diet versus exercise on breast cancer risk. It was published this week in Cancer Epidemiology, Biomarkers & Prevention.
