Cancer Screening

Both screening and prevention can reduce mortality from cancer. Screening detects abnormalities before they are clinically apparent, allowing for intervention either before cancer develops or at an early stage, when treatment is most often effective. Prevention strategies focus on modifying environmental and lifestyle risk factors that promote cancer. It is estimated that 50 percent of cancer is preventable . Many cancers are preventable. Basic lifestyle changes can have a tremendous impact on the rates of cancer. The fact that such changes also protect against other chronic diseases (cardiovascular disease, stroke, and diabetes) makes the case for prevention even more compelling.
