Physical activity helps regulate body weight by expanding calories and building lean muscle mass. Maintaining a healthy weight is crucial for cancer prevention, as excess body fat is linked to an increased risk of various cancers, including breast, colorectal, and endometrial cancers.
Regular exercise improves insulin sensitivity, which is essential for proper glucose metabolism. Insulin resistance, often associated with obesity and sedentary behavior, can contribute to the development of certain cancers, including pancreatic and colorectal cancers.
Chronic inflammation is a key factor in cancer development. Physical activity helps reduce inflammation in the body, which can contribute to a lower risk of cancer. Exercise triggers anti-inflammatory responses that support overall health.
