A new research review has found that regular physical activity significantly decreases risk for 13 different types of cancer including that of the colon, breast, and lung. For the analysis, researchers pooled data from 12 U.S. and European studies to create a database of 1.4 million adults, aged 19 to 98. They then examined whether self-reported physical activity made a difference in risk of 26 cancers.
The report found that even just a couple of hours a week of physical activity significantly reduces individuals’ risk of cancer. And, if you can do more, the cancer risk reduction is even greater. In the study cancer risk continued to decline as time spent doing activity increased. Prior research has linked exercise to reduced risk of breast and colon cancer, but the role of activity on other types of cancer has yet to be clearly established. In this analysis in addition to breast, lung, and colon cancer, activity significantly reduced the risk of getting cancers of the esophagus, liver, kidney, stomach, endometrium, rectum, bladder, head and neck, as well as leukemia and myeloma. Activity level appears to especially moderate risk of esophageal cancer. The study found doing regular activity reduced risk by 46%. Activity also had a very marked impact on lung cancer risk with a 26% reduction.
No one is certain why exercise seems to help fend off cancer. Activity has multiple beneficial effects that likely contribute to its cancer prevention benefits. Physical activity reduces levels of hormones, such as estrogen, that have been linked to different cancers, especially breast cancer. Activity also helps control levels of insulin and insulin-like growth factor which can promote tumor formation and growth. People who work out also tend to have lower levels of inflammation. Their cells appear to be subject to less oxidative stress, and are more capable of repairing damaged DNA that might cause cancer.
What to do: Get moving! You do not have to be a gym rat to realize the health benefits of activity. Do what you can. Some is always better than none. Current federal activity guidelines call for doing at least 150 minutes of moderate-intensity activity (such as brisk walking) a week, or 75 minutes of vigorous activity (such as jogging). These recommendations are primarily based on maintaining heart health but also good guidelines for cancer risk reduction. How vigorous an activity is depends on your fitness level but in general other examples of moderate intensity exercise include walking briskly (3 miles per hour or faster), water aerobics, bicycling slower than 10 mph, doubles tennis, and ballroom dancing. Vigorous activities include race walking, jogging/running, lap swimming, singles tennis, aerobics, bicycling more than 10 mph, jumping rope, and hiking uphill.
