New research from the University of Kentucky highlights a frequently overlooked benefit of exercise: its role in reducing cancer risk.
The research indicates that adults who engage in higher levels of physical activity have a lower risk of developing certain cancers, including breast, kidney, lung, colon, endometrial, esophageal, bladder, and stomach cancers. This finding underscores the importance of incorporating regular physical activity into a preventative health strategy.
How it Works
Physical activity may reduce cancer risk by decreasing chronic inflammation and regulating hormones that contribute to cancer development. It also supports a healthy immune system, which can fight off abnormal cells before they progress.
Increasing activity also reduces the amount of time spent sitting. Research shows that prolonged periods of inactivity increase the likelihood of developing certain cancers and other health conditions. Exercise is also known to aid in weight loss, which can positively influence cancer risk, as excess adipose tissue can contribute to inflammation, increased estrogen levels, and elevated insulin and growth factors.
The Solid News
Any type of physical activity is beneficial for the body. Adults are recommended to get at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous-intensity activity each week. Moderate-intensity activities include dancing, brisk walking (around 5 km/h), yoga, golfing, and gardening. Vigorous-intensity activities include running, swimming, jump rope, and cycling at a fast pace (around 16 km/h).
To put this in perspective, a recent study showed that the risk of cancer for people who take 7,000 steps a day is 11% lower than for those who take 5,000 steps a day. Similarly, those who take 9,000 steps have a 16% lower risk. The same study revealed that individuals with the highest levels of daily physical activity had a 26% lower risk of developing cancer compared to those with the lowest levels.
Get Moving
Exercise can make a significant difference in preventing cancer, a leading cause of death. Any amount of physical activity is beneficial, no matter how slight or large. Anyone can start somewhere by setting small goals and gradually increasing their activity level.
