Daily exercise such as walking can prevent and even reverse heart disease and diabetes， and prevent cancer and strokes.
The money will also go to community organizations， clinics and nutritionists who are being encouraged to work together to educate people at risk of diabetes about what they can do to prevent it and encourage more cancer screening.
The American Cancer Society estimates that half of all cancers can be caught by screening， including Pap tests for cervical cancer， mammograms for breast cancer， colonoscopies， and prostate checks.
If such cancers were all caught by early screening， the group estimates that the survival rate for cancer would rise to 95 percent.
