Colon cancer and rectal cancer are the most common malignancies in the human body. The incidence rate is second only to cervical cancer, breast cancer and gastric cancer, accounting for the fourth place in malignant tumors. Its incidence in the gastrointestinal tract is second only to gastric cancer. A total of 501 cases of colon cancer and rectal cancer were treated in our hospital from September 1957 to November 1977, including 100 cases of right colon cancer, accounting for 20% of colorectal cancer. Now 100 cases of right colon cancer are analyzed clinically, and the problems of early diagnosis and misdiagnosis of right colon cancer are discussed. Clinical data I. General information: There were 58 males and 42 females in this group. The ratio of male to female was: 1.38:1. The youngest were 18 years old and the oldest were 85 years old, of which 68 cases (68%) ranged from 31 to 60 years old and the average age was 43 years old. (Table 1 shows the relationship between the onset and age) The incidence of colorectal cancer in foreign countries is about 10 years earlier.
