From Cancer Statistics, 2013:
A new report from the American cancer society finds the overall death rate from cancer has gone down 20 percent from its peak in 1991.
The drop is even greater for the big four -- breast, lung, colorectum and prostate cancer.
Dr. Otis W. Brawley of the American Cancer Society says that “fewer Americans are smoking. After that it’s improvements in early detection of cancer and improvements in treatments of cancer.”
