在2010年7月出版的影響因子為87.92（MedSci 各細分學科影響因子*0查詢）的學術刊物CA：A Cancer Journal for Clinicians上，美國癌癥學會（American Cancer Society）公布了美國癌癥的統計數據。報告的主要要點如下：2010年，美國查出1529560新發癌癥病例，也就是說每天新發4190人。新發癌癥中，男性789620例，前三位是前列腺癌（28%）、肺癌（15%）和直腸癌（9%），女性739940例, 前三位是乳腺癌（28%），肺癌（14%）和直腸癌（10%）；2010年，全美有569490人死于癌癥，其中男性299200例，女性270290例, 也就是說每天死亡1560人。 2000年到2006年間，男性癌癥發病率每年下降1.3%；從1998年到2006年，女性癌癥發病率每年下降0.5%。男性癌癥發病率下降較多是因為肺癌、前列腺癌和直腸癌發病率明顯下降。女性癌癥死亡率下降主要因為乳腺癌和直腸癌發病率明顯下降; 由于在癌癥預防、檢測和治療方面的進步，從1990年到2006年，美國男性癌癥死亡率下降21%，其中女性患者死亡率下降12.3%，期間被癌癥奪去生命者減少76.7萬。在所有癌癥中，男性的三大殺手是肺癌（29%）、前列腺癌（11%）和直腸癌（9%）；女性的三大殺手是肺癌（26%）、乳腺癌（15%）和直腸癌（9%）（tangdl2000 編譯）。 （生物谷Bioon.com）   原文出處： CA Cancer J Clin 2010 doi: 10.3322/caac.20073  Cancer Statistics, 2010 Ahmedin Jema l, DVM, PhD 1, Rebecca Siege l, MPH 2, Jiaquan Xu, MD 3 and Elizabeth Ward, PhD 4 1.

Mortality Statistics Branch, Division of Vital Statistics, National Center for Health Statistics, Centers for Disease Control and Prevention, Hyattsville, MD 4. Surveillance and Health Policy Research, American Cancer Society, Atlanta, GA Each year, the American Cancer Society estimates the number of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data regarding 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. Incidence and death rates are age-standardized to the 2000 US standard million population. A total of 1,529,560 new cancer cases and 569,490 deaths from cancer are projected to occur in the United States in 2010. Overall cancer incidence rates decreased in the most recent time period in both men （1.3% per year from 2000 to 2006） and women （0.5% per year from 1998 to 2006）, largely due to decreases in the 3 major cancer sites in men （lung, prostate, and colon and rectum [colorectum]） and 2 major cancer sites in women （breast and colorectum）. This decrease occurred in all racial/ethnic groups in both men and women with the exception of American Indian/Alaska Native women, in whom rates were stable. Among men, death rates for all races combined decreased by 21.0% between 1990 and 2006, with decreases in lung, prostate, and colorectal cancer rates accounting for nearly 80% of the total decrease. Among women, overall cancer death rates between 1991 and 2006 decreased by 12.3%, with decreases in breast and colorectal cancer rates accounting for 60% of the total decrease. The reduction in the overall cancer death rates translates to the avoidance of approximay 767,000 deaths from cancer over the 16-year period. This report also examines cancer incidence, mortality, and survival by site, sex, race/ethnicity, geographic area, and calendar year. Although progress has been made in reducing incidence and mortality rates and improving survival, cancer still accounts for more deaths than heart disease in persons younger than 85 years. Further progress can be accelerated by applying existing cancer control knowledge across all segments of the population and by supporting new discoveries in cancer prevention, early detection, and treatment.
