General Improvement in Cancer Mortality Rates
Much like the slow and steady lengthening of life expectancy, there is a general improvement in cancer treatment outcomes thanks to progress across the board in modern medicine: "The continued drop in overall cancer mortality rates over the last 20 years has averted more than three-quarters of a million (767,000) cancer deaths according to a new report from the American Cancer Society. The American Cancer Society's annual Cancer Statistics article reports that the overall death rate from cancer in the United States in 2007 was 178.4 per 100,000, a relative decrease of 1.3 percent from 2006, when the rate was 180.7 per 100,000, continuing a trend that began in 1991 for men and 1992 for women. In that time, mortality rates have decreased by 21 percent among men and by 12 percent among women, due primarily to declines in smoking, better treatments, and earlier detection of cancer. ... Cancer incidence rates decreased in men 1.3 percent per year from 2000 to 2006 and in women 0.5 percent per year from 1998 to 2006. Death rates for all cancer sites combined decreased 2 percent per year from 2001 to 2006 in males and 1.5 percent per year from 2002 to 2006 in females."
