What Role Do Environmental Factors Play in Cancer Variations?
Environmental factors significantly influence cancer risk and variations. Carcinogens such as tobacco smoke, ultraviolet (UV) radiation, and certain chemicals can damage DNA and lead to mutations. Lifestyle choices, including diet, physical activity, and alcohol consumption, also impact cancer risk. For example, diets high in processed meats and low in fruits and vegetables have been linked to an increased risk of colorectal cancer. Regular physical activity and maintaining a healthy weight can reduce the risk of several cancers, including breast and colon cancer.
