Focus: Cancer statistics, 2011 (USA)

Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. A total of 1,596,670 new cancer cases and 571,950 deaths from cancer are projected to occur in the United States in 2011. Overall cancer incidence rates were stable in men in the most recent time period after decreasing by 1.9% per year from 2001 to 2005; in women, incidence rates have been declining by 0.6% annually since 1998. Overall cancer death rates decreased in all racial/ethnic groups in both men and women from 1998 through 2007, with the exception of American Indian/Alaska Native women, in whom rates were stable. African American and Hispanic men showed the largest annual decreases in cancer death rates during this time period (2.6% and 2.5%, respectively). Lung cancer death rates showed a significant decline in women after continuously increasing since the 1930s. The reduction in the overall cancer death rates since 1990 in men and 1991 in women translates to the avoidance of about 898,000 deaths from cancer. However, this progress has not benefitted all segments of the population equally; cancer death rates for individuals with the least education are more than twice those of the most educated. The elimination of educational and racial disparities could potentially have avoided about 37% (60,370) of the premature cancer deaths among individuals aged 25 to 64 years in 2007 alone. Further progress can be accelerated by applying existing cancer control knowledge across all segments of the population with an emphasis on those groups in the lowest socioeconomic bracket.

  1. Increased screening for colorectal cancer during the last decade has put a sharp dent in both the prevalence of the No. 2 cancer killer and in the number of deaths resulting from it, the Centers for Disease Control and Prevention said Tuesday.
    As screening for the disease among those ages 50 to 75 increased from half to two-thirds of the eligible population, the prevalence rate fell from 52.3 cases per 100,000 in 2003 to 45.4 per 100,000 in 2007.
    Those declines represent 66,000 fewer cancers during the period and 32,000 fewer deaths, the agency found. But there are still 22 million Americans in the eligible age group who are not being screened, according to the report.
