The American Cancer Society estimates that about one-third of cancer deaths in 2012 will be caused by tobacco use and another third will be related to overweight or obesity, physical inactivity, and poor nutrition.
The 5-year relative survival rate for all cancers diagnosed between 2001 and 2007 is 67%, up from 49% in 1975-1977. Cancer death rates are continuing to fall, dropping by 1.8 percent per year in men and 1.6 percent per year in women between 2004 and 2008.
