Adopting a healthy lifestyle significantly reduces lifetime cancer risk
Extensive prospective cohort studies and comprehensive reviews consistently demonstrate that adopting a healthy lifestyle—including regular physical activity, a nutritious diet, maintaining healthy body weight, and avoiding tobacco and excessive alcohol—substantially reduces lifetime cancer risk.
Multiple large-scale prospective studies and reviews (such as UK Biobank analyses and population-based cohorts) consistently show that favorable lifestyle scores significantly lower the incidence and mortality of various cancers, independent of genetic risk.

The review synthesizes evidence showing that healthy dietary patterns, regular physical activity, weight management, and avoidance of carcinogens are consistently associated with a lower incidence of several cancers.
