A new government report on cancer shows deaths fell in the U.S. from 2000 to 2009, by an average of 1.8 percent a year for men and 1.4 percent for women. But a professor of medicine and engineering at the University of Southern California says the decline is not nearly enough. He says preventative measures like taking baby aspirin daily, eating "real food," and "moving during the day" are the key to significantly reducing the cancer death rate.

The report says less smoking and early detection also helps. The study also shows there is a growing number of cancers associated with the human papilloma virus. Researchers say that highlights the need for increased HPV vaccination.
