Recently, it was reported that Qi Sheng Nie Weiping was suffering from rectal cancer, which once again aroused public attention to the "health killer" of colorectal cancer. According to the latest statistics, colorectal cancer has ranked third in the incidence of tumors and the fifth in mortality in China, and ranks the second in tumor incidence and the fourth in mortality among the urban population. The rate is increasing at a rate of 4.71% per year.
The office crowd is one of the key populations affected by colorectal cancer due to high work pressure, unreasonable living and eating habits, and a lot of entertainment. How to prevent it effectively?
The key is prevention
According to experts, colorectal cancer is usually called colorectal cancer, including colon cancer and rectal cancer. It is a common malignant tumor, and its incidence is rising. According to the "Annual Report on Cancer Registration in China" published in 2012, the domestic incidence of colorectal cancer is about 29.44/100,000, and the mortality rate is 14.23/100,000. The incidence of colorectal cancer in some developed cities is close to or even higher than that of developed countries. . With the process of urbanization in China, the westernization of dietary structure, and the aging of the social population, the incidence and mortality of domestic colorectal cancer will further increase.
The occurrence of colorectal cancer is a multi-factor and multi-stage process, which is the result of the interaction between the internal factors of the human body and the external factors of the environment. Epidemiological studies have shown that environmental factors account for about 80% of the attributable risk of colorectal cancer, mainly related to high-fat, high-calorie, low-fiber diet and lack of physical activity. Another 20% of colorectal cancer is related to genetic background.
Currently, the treatment of colorectal cancer is mainly surgical resection, supplemented by chemotherapy and radiotherapy. The 5-year survival rate after radical resection of colorectal cancer is about 50%, and the 5-year survival rate after radical resection in early stage patients can be as high as 90%. "So if you want to prevent colorectal cancer, increase the radical cure rate, and prolong survival, the key lies in etiological prevention and early diagnosis."
First shut up
To prevent and treat colorectal cancer, we must first "control your mouth" and maintain a good diet.
Experts say that in your daily diet, you should eat more digestible foods with high protein, high vitamins, and low fat, and reduce fatty foods, because a fat diet will increase the concentration of bile acids in the intestines, and high concentrations of bile acids can promote Cancer effect. Fish, poultry, lean meat, and low-fat dairy products should be used to replace meat with too much animal oil, and boiled and steamed foods should replace fried foods. Eat more fresh vegetables and fruits, especially yellow-green vegetables rich in vitamin A and vitamin C. The diet should not be too fine, proper intake of some coarse grains can promote bowel movements and reduce the retention of carcinogens in the intestines.
Experts especially remind you to eat less salted and smoked foods such as sausage, ham, bacon, salted fish, etc., or high-temperature grilled and fried foods. Pickled foods contain carcinogenic nitrosamine compounds. High-protein foods will produce heterocyclic amines after high temperature or frying, which have obvious carcinogenic and mutagenic effects. The appropriate amount of vitamin D and calcium supplementation can combine with fatty acids in the intestinal tract to form insoluble compounds and be excreted from the body. It is worth mentioning that eating 6 slices of garlic a week can reduce the chance of colorectal cancer.
From an international perspective, Japan is a very good example of controlling the incidence of colorectal cancer. According to surveys, the amount of fat in the current Japanese diet only accounts for 12% of the total calories, and the incidence of colorectal cancer is significantly lower than in other countries and regions.
Pay attention to constipation
To prevent and treat colorectal cancer, it is necessary to develop a good lifestyle. The first is to quit smoking. A large amount of toxic and harmful substances are produced during the burning of tobacco, which can induce the occurrence of many kinds of malignant tumors such as colorectal cancer and lung cancer.
For office workers, to prevent and treat colorectal cancer, constipation must be prevented first. Stool stays in the intestinal cavity for too long, which will cause the toxins in the stool (amines, phenols, ammonia, azobenzene and other chemical carcinogens, indole, methyl indole, hydrogen sulfide and other toxic products) and intestines The mucosal contact time is prolonged, and the intestinal wall becomes cancerous under the prolonged stimulation of toxins.
Cui Long specifically pointed out that many people believe that oral aloe vera, rhubarb, or drinking weight loss tea can reduce the symptoms of constipation. In fact, the effect is just the opposite. These products will accumulate on the intestinal wall due to the anthraquinones contained in these products, causing the intestinal tract Melanosis, and intestinal melanosis is one of the culprits of colorectal cancer.
To improve constipation, the key is to drink more water, exercise more, maintain a good diet, eat more fiber foods, and appropriate intake of honey, yogurt, etc. At the same time, weight control and regular physical activity help to defecate and prevent the occurrence of colorectal cancer.
Experts point out that the occurrence of colorectal cancer is a multi-stage process from polyps-adenoma-adenocarcinoma. Polyps and adenomas are a type of benign disease of the digestive tract. Patients with intestinal polyps should be removed in time, usually through minimally invasive treatment under endoscopy.
Once colorectal polyps have tumorous lesions, they usually show changes in bowel habits and traits, such as decreased or increased bowel movements, thinner stools, bloody stools (dark red or bright red blood mixed with stool, or wrapped in Stool surface), there is mucus in the stool, incomplete defecation or abdominal pain related to defecation, etc. Some patients also experience unexplained weight loss or anemia. When the above symptoms are found, effective and reliable colonoscopy should be carried out in time to clarify the focus and cause of gastrointestinal bleeding. Do not think that hemorrhoids are not taken seriously, leading to delays in treatment.
Nowadays, most people in the office have the benefits of an annual physical examination. However, many people, especially young and middle-aged people, only value the results of blood tests and imaging examinations, and often ignore or reject digital anal examinations. You should know that rectal cancer accounts for 60% of colorectal cancer patients in China, and 60%-70% of rectal cancers are low rectal cancers. A simple digital anal examination can be initially diagnosed. Therefore, we must pay attention to the digital anal examination items in the physical examination.
Experts also emphasized that people with a history of cholecystectomy and a history of schistosomiasis or gastrointestinal polyps have a significantly higher incidence of colorectal cancer than the normal population and require regular colonoscopy. If one of the immediate family members has colorectal cancer, especially if they have more than two consecutive generations, the risk of colorectal cancer is nearly 20 times higher than that of the general population. It is recommended that such people should pay special attention to regular follow-up inspections.
