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.
It was published today in JAMA Internal Medicine.
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. Continue reading
It’s “Back to school” time and that brings challenges in keeping kids active and healthy in the 21st century. In decades past, school provided much more than academic education; it also provided an environment conducive to the development of social and life skills. Lessons learned on the playground included important social skills such as cooperation, teamwork, conflict resolution, and peer communication. Physical education class provided an outlet to release energy, and establish the important lifestyle habit of physical activity on a daily basis.

With recess and physical activity time being cut to make more time for classroom learning, the struggle to keep kids healthy and active is harder than ever before. The sad truth is kids are expected to spend the majority of their day “sitting”, contributing to skyrocketing childhood obesity rates and overall health concerns — including increased cancer risk — for our next generation.
That said, the challenges don’t end when the bell rings. Kids today have succumbed to the “technology takeover”, spending more time living in the “virtual” world than in the real one. While kids in previous generations would play outside afterschool until dinner time, kids today run home to video games, television shows, text messages, and social media, increasing the amount of time they are sedentary.
We all recognize the issues and we want to overcome them, but what motivates a child to want to be active? To answer this question we must remove our “adult” motivations (lose Continue reading
Like most American women (and men), most breast cancer survivors may also not be exercising enough to reap its many health benefits, suggests a new study. Yet it’s African American survivors who are even less likely to meet the activity recommendations compared to white women.
The study was published today in Cancer. It’s important because a lot of research has linked regular physical activity among survivors to to better health and longer lives.
AICR recommends that survivors follow the same activity recommendations as for prevention. Here’s a few examples of studies that have found how activity benefits survivors.
In this study, about 1,700 women diagnosed with breast cancer reported their activity habits both before their diagnosis and six months afterwards. The women ranged in age from 20 to 74, and about half were African American. Researchers converted the women’s activity habits into a common unit of measure: metabolic equivalent hours (METs).
Six months after diagnosis, 59 percent of all the patients reported being less active. Only about one-third of women reported they were active at least 150 minutes per week compared to 60 percent before diagnosis. Continue reading
