AICR’s evidence shows that having too much body fat increases risk for eleven cancers. But researchers are looking at whether losing weight, once overweight, would lead to lower risk for these cancers. Now a new study from researchers at Fred Hutchinson Cancer Research Center shows how weight loss – through diet alone or diet and exercise – might change pro-cancer substances in the body.
The 12-month controlled trial of 439 healthy, postmenopausal women with overweight/obesity included 4 randomized groups: calorie restriction diet; moderate activity (goal of 3.75 hours per week), diet and exercise, and no intervention. Researchers wanted to see if these lifestyle changes would affect four substances in the body (biomarkers) that influence formation of blood vessels needed for tumor growth. Fat cell growth also requires a greater blood supply, so these biomarkers are also associated with increasing fat tissue.
School’s out for the summer and kids are ready to play! This is a great time to make healthy habits part of your family’s summer plans. Give your kids a start for lifelong cancer protection by helping them be active. For adults, AICR research shows that moving for at least 30 minutes daily lowers the risk for post-menopausal breast, colorectal, and endometrial cancers.
To find out how Americans will be getting active, the National Recreation and Park Association asked about favorite summer outdoor activities in a recent survey. Half of those surveyed said that going for a walk or a hike is one of their favorites. Walking and hiking are great ways to explore nature in your local park, on a National Park trail, or to find a new shop in your neighborhood. At the same time you’ll boost fitness, strengthen muscles and build endurance.
A large new study that pooled together data from a dozen studies found that those who walk, swim, jog or do other sorts of activity the most are at lower risk of developing 13 different types of cancer compared to those who are the least active. The study included almost 1.5 million participants and supports the importance of physical activity for lower cancer risk.
AICR research shows that activity lowers risk of colon, breast, and endometrial cancers. There is some evidence being active may play a role in other cancers, but many of these studies are relatively small; AICR continues to analyze the research – including this study – as part of its Continuous Update Project.
The strength of this study was that it could pool together cancers that are not as common. Here, researchers included 12 population studies from the United States and Europe to look at how physical activity links to 26 cancer types. All together, the studies included 1.4 million men and women, ages 18 to 98. The average age was 59. Read more… “Massive new study, activity cuts risk of 13 cancers”
