Colon, Rectum ＆amp; Anus (C18-C21)
In 2016, colorectal cancer cases accounted for 7% of all cancer cases in Henan cancer registration areas with the crude incidence of 18.77/105, ASR for China 14.68/105 and ASR for World 14.47/105.The incidence in males was 20.09/105, and 17.38/105 in females.It was 1.28 times in males as high as that in females and it was 1.3 times in urban areas as that in rural areas.The crude mortality of Colorectal cancer in 2016 was 9.16/105, ASR for China was 6.91/105 and ASR for World 6.84/105.The mortality in males was 10.15/105, and 8.1/105 in females.The cumulative rates of incidence and mortality from 0 to 74 years old were 1.74% and 0.73%, respectively.(Table 5-5)

结直肠肛门恶性肿瘤年龄别发病率和死亡率在0~39 岁年龄段处于较低水平，40 岁以后快速上升，在80~组达到高峰，男性高于女性。城乡和不同地区年龄别率的水平虽然有一定的差异，但总体趋势类同。（图5-5a ～图5-5f）
The age-specific incidence rate of colorectal cancer were relatively low before 40 years old and increased dramatically since 40 years old, reaching the peak at the age group of 80~.The age-specific incidence and mortality rates varies between the urban and rural areas, but they have the similar trends.(Figure 5-5a~figure 5-5f)
