Cancer report emphasizes healthy living.

While the number of deaths from cancer has been declining, many malignancies could be prevented by exercising, eating right, maintaining a healthy weight and not smoking, a new federal report finds.

The President's Cancer Panel issues a report every year that focuses on one aspect of what is happening in the United States in terms of cancer.

This year's effort "centers on lifestyle changes and two issues that are actually quite different," said panel member Margaret L. Kripke, executive vice president and chief academic officer at the University of Texas M. D. Anderson Cancer Center in Houston.
