Academician Fan Daiming: who is a high-risk population of colorectal cancer? Sohu – Sohu health paper Wu Shinan in recent 20 years, along with the diet and the change of living environment in China, colorectal cancer (CRC) incidence increased significantly, about 400 thousand new patients a year, the growth rate was two times the world average speed. The incidence of the disease in China has ranked fourth in the malignant tumor, the mortality rate ranked the fifth place, more than Europe, the United States, Japan and other developed countries. Worldwide, colorectal cancer is tending to be younger, with an average age of 60 years or more from the original age of about 45 years old. Colorectal cancer is a common malignant tumor of gastrointestinal tract in patients with early symptoms are generally hidden, not easy to find, sometimes being mistaken as chronic colitis, hemorrhoids, diarrhea, adhesive ileus, intestinal polyps and ulcerative colitis treatment. Once found obvious symptoms, most patients to have advanced, the treatment effect, so it is a "coming of colorectal cancer". But as a kind of malignant tumor is preventable and curable, "invisible" colorectal cancer is possible "without a trace", but the key lies in the "early". In the recently held Affiliated Hospital of Yan’an University academician workstation construction project and Yanan city teachers free of gastrointestinal cancer charity screening project to start the meeting, pointed out that Chinese Academy of Engineering vice president Fan Daiming, colorectal polyps and adenomas have changed obviously before cancer, but these symptoms early itself is difficult to detect, can only rely on a variety of detection methods found. Therefore, high-risk groups to carry out regular colorectal cancer screening, early detection, early diagnosis, early treatment, as far as possible to prevent the occurrence of malignant cancer. Data show that in the early diagnosis of colorectal cancer, prolong the life expectancy of patients, early cancer cure rate of more than 90%; phase II cancer 5 years survival rate is more than 70~80%; lymph node metastasis for stage III cancer, life expectancy decreased to 50%~76%; stage IV colorectal cancer with metastasis is rarely cure. Thus, the early screening of colorectal cancer can not be ignored, especially for high-risk groups, early screening is a means to reduce the possibility of cancer. What are the high risk of colorectal cancer? Fan Daiming told the Sohu health reporter, 45 years old, male, intestinal polyps Benign bowel disease history of the population, have a family history of colorectal cancer population, live in areas of high incidence of colorectal cancer and people with a history of smoking, obesity and other groups are the high-risk category. These people should be actively concerned about and understanding of colorectal cancer screening, and according to the doctor’s advice and choose their own rectal examination, fecal occult blood test, colonoscopy and Septin9 gene screening using the public detection by means of comprehensive screening. In addition to early detection, early prevention of colorectal cancer is a "civilized disease" is also very important. Deputy director of the national clinical research center of digestive diseases executive vice president Wu Kaichun pointed out that the The Fourth Military Medical University Xijing Hospital of digestive diseases, lifestyle and eating habits and nutritional level have very close relationship with colorectal cancer. In daily life, if you want to achieve a good preventive effect, it is necessary to exercise more, drink plenty of water, eat less junk food, eat less red meat, more.
