大肠癌在我国的发病率为17/10万,约占全部肿瘤排队的4—6位。由于患者和医生缺乏警惕性,早期大肠癌常被误诊为慢性痢疾或痔疮出血,而丧失了手术治疗机会。究其原因,大多应归罪于患者自己不愿接受甚至拒绝直肠指检,而某些医生也嫌脏怕臭而免去这一“麻烦”。 The incidence of colorectal cancer in China is 17/100,000, accounting for about 4 to 6 of all tumors in the queue. Due to the lack of vigilance of patients and doctors, early colorectal cancer is often misdiagnosed as chronic diarrhea or hemorrhoids hemorrhage, and lost surgical treatment. The reason is mostly attributed to the patient’s unwillingness to accept or even reject the rectal examination, and some doctors are also afraid of odor and get rid of this “trouble.”
