Why exercise has a crucial role in cancer prevention, risk reduction and improved outcomes (research)

• Harvard Alumni Study (1995): This study found that men who engaged in vigorous physical activity had a 68% lower risk of colon cancer compared to those who were less active. The study highlighted the importance of sustained physical activity over time.
• Women’s Health Study (2007): This study observed that women who engaged in high levels of physical activity had a 30% to 40% lower risk of breast cancer compared to those who were less active. The reduction in risk was more pronounced in women who maintained a consistent exercise regimen.
• European Prospective Investigation into Cancer and Nutrition (EPIC) Study (2008): This large-scale study found that higher levels of physical activity were associated with a 50% lower risk of colon cancer. The study included participants from multiple countries across Europe and considered various forms of physical activity.
• MET-Ex Study (2020): A more recent study examined the relationship between MET-hours per week and cancer risk reduction. It found that individuals who engaged in 7.5 to 15 MET-hours per week of vigorous exercise (equivalent to 150-300 minutes of moderate activity) had a 30% to 60% lower risk of several types of cancer, including breast, colon, and endometrial cancer.
• American Cancer Society Cancer Prevention Study II (2014): This study followed over 140,000 men and women and found that those who engaged in the highest levels of physical activity had a 25% to 50% lower risk of various cancers, including lung, breast, and colon cancer.
