Among cancers that affect both men and women, colorectal cancer is the second leading cause of cancer death. In 2007 (the most recent year for which data are available), >142,000 persons received a diagnosis for colorectal cancer and >53,000 persons died. Screening for colorectal cancer has been demonstrated to be effective in reducing the incidence of and mortality from the disease. In 2008, the U.S. Preventive Services Task Force (USPSTF) recommended that persons aged 50-75 years at average risk for colorectal cancer be screened by using one or more of the following methods: high-sensitivity fecal occult blood testing (FOBT) every year, sigmoidoscopy every 5 years with FOBT every 3 years, or colonoscopy every 10 years.
在影响男性和女性的癌症中，结直肠癌是癌症死亡的第二大主要原因。2007年（可获取数据的最近一年），超过14.2万人被诊断患有结直肠癌，超过5.3万人死亡。事实证明，结直肠癌筛查可有效降低该疾病的发病率和死亡率。2008年，美国预防服务工作组（USPSTF）建议，年龄在50至75岁、患结直肠癌平均风险的人群，应使用以下一种或多种方法进行筛查：每年进行高灵敏度粪便潜血试验（FOBT）；每5年进行一次乙状结肠镜检查，每3年进行一次FOBT；或每10年进行一次结肠镜检查。
