Colorectal cancer screening is urgent According to the Beijing Municipal Health Bureau Health Podcast: The mortality rate of malignant tumors in Beijing has been increasing at an accelerated rate, ranking first among the causes of death of the city’s residents in 2007, with bowel cancer becoming the most frequent tumor after lung cancer and liver cancer. Therefore, we must pay attention to intestinal health. Carrying out census of asymptomatic people According to Li Shengming, director of the Department of Surgery IV of the City Hospital of Traditional Chinese Medicine.
93% of colorectal cancer comes from adenoma (a kind of precancerous lesion), which takes 5~7 years to develop from adenoma to cancer. Since most early colorectal cancers and precancerous lesions are asymptomatic, but they may bleed in small amounts, regular initial screening with fecal occult blood test and colonoscopy for those who are positive is an important means of early detection of colorectal cancer, and is also an internationally accepted screening method. Fecal occult blood test is to detect the trace amount of blood in the stool that cannot be seen by the eyes, thus indicating the intestinal health condition of people. It is worth noting that precancerous colorectal cancer and early stage cancer are often asymptomatic and not easily detected, while symptomatic patients are mostly in the middle and late stages when they are seen, some of them have metastasized or combined with many complications, and the mortality rate is extremely high. Therefore, to carry out screening of asymptomatic people, detect early cancer and precancerous lesions and treat them is the key to reduce the incidence of colorectal cancer and improve the survival rate of colorectal cancer patients. Early diagnosis and treatment can approach the state of cure Colorectal cancer is divided into four stages according to the degree of infiltration and the presence or absence of metastasis.
Because of deep infiltration or metastasis, the quality of life of patients in stages III and IV is low and the prognosis is poor. We have compared the census of “asymptomatic people” and “symptomatic patients”: the chance of early cancer and earlier cancer in the former is 91.7%, while the chance of early colorectal cancer in the latter group is only 41.1%; the chance of treatment and treatment effect of the former is also much better than that of the latter. The former was also much better than the latter in terms of treatment access and outcome. We also conducted continuous colorectal cancer screening for a group of 3002 people over 50 years old, and found 21 cases of colorectal cancer and 497 cases of colorectal adenoma in 16 years, and 94.44% of colorectal cancer was early cancer; colorectal adenoma was removed under colonoscopy, and only one case of cancer was found in the follow-up, which fully affirmed the role of screening for asymptomatic people in colorectal cancer prevention and treatment. People over 30 years old should have fecal occult blood test every year, and colorectal cancer and precancerous lesions are not only the diseases that the elderly are prone to, but also the young and middle-aged people should pay attention to them. For people at high risk of colorectal cancer, fecal occult blood test should be performed along with cancer risk prediction. The high-risk groups for colorectal cancer include: people who have had colorectal cancer or colorectal adenoma; immediate family members who have colorectal tumors and multiple relatives who have other malignant tumors; patients with ulcerative colitis that does not heal for more than 10 years; patients who have pelvic tumors and receive radiotherapy; family members with familial adenomatous polyposis and hereditary non-polyposis colorectal cancer. These high-risk groups have 2 to 4 times higher risk of colorectal cancer than the general population, and the age of onset is small, so it is more important to pay close attention to intestinal health, seek medical consultation promptly with symptoms and regular screening without symptoms.
