A healthy lifestyle may contribute positively to cancer prevention.

Out of the 10 million cancer cases recorded worldwide annually, 5-10% are due to genetic defects while environmental and lifestyle factors account for about 90-95% of these cases. These factors are responsible for 75-80% of all cancer-related deaths. Thus, cultivating healthy habits, such as exercising regularly, minimizing stress, smoking cessation, limiting calorie and meat intake, avoiding alcohol, undergoing regular medical checkups and vaccinations, minimizing contact with pollutants, avoiding direct exposure to sunlight, and ingesting large quantities of fruits, vegetables, and whole grains may help to prevent cancer. A healthy lifestyle is, therefore, essential to preventing cancer.
