So what exactly counts as physical activity? Well, just like exercising for everyday health, any movement that uses skeletal muscle and requires more energy than rest can be counted as healthy physical activity that can reduce the risk of cancer. Whether the movement you choose is structured or unstructured, it is only a sedentary lifestyle that is dangerous.
Walking your dog, tackling the playground with your kids, or doing household chores can reduce your risk of cancer and other diseases just as much as lifting weights, running a marathon, or playing sports can.
Aside from preventative measures, cancer patients can improve their quality of life through exercise. In general, exercise can improve the body’s response to treatment no matter the stage or type of cancer. A healthy body is more resilient. Regular exercise has been shown to reduce treatment-related fatigue, maintain heart and lung fitness, maintain physical ability and strength, and reduce feelings of anxiety and depression. In some observational studies, exercise has also been associated with better survival rates for certain cancers. As a rule of thumb, exercise will always improve overall health.
