Large intestine is the general term for colon and rectal cancer, colorectal cancer is large intestinal mucosa in the environmental or genetic factors such as carcinogenic under the action of a variety of malignant lesions with poor prognosis, the mortality rate is higher. Colorectal cancer is colorectal cancer of epithelial origin. Is one of the most common gastrointestinal malignancy. Here are a few of colorectal cancer prevention:
Colorectal cancer prevention (1) improve dietary habits. Reasonable arrangements for the daily diet to eat more fresh fruits and vegetables are rich in carbohydrate and crude fiber foods, an appropriate increase in staple food grains, cereals should not be too small and too fine proportion. Changes in meat and high-protein food-eating habits. Eat less high fatty foods. In particular, to control the intake of animal fat. Because of the high-fat, high animal protein diet on the one hand to stimulate the secretion of bile. Intestinal bile increased bile acid and cholesterol containing mainly so the fecal bile acid and cholesterol content increased, the other kind of diet can lead to large intestine the contents (commonly known as fecal juice) in the active growth of fusiform bacilli spores of the bacteria is an anaerobic bacteria, such bacteria are rich in 7 – de Jing-based enzyme which acts on bile acid and cholesterol, can cause the formation of cancer by polycyclic unsaturated substances.
The low-fiber diet, resulting in less waste, less stimulation of the large intestine, large bowel is slow, the colon cancer-causing substances in the extended memory, but also the role of anaerobic bacteria spores fusiform time increases in cholesterol, resulting in more carcinogenic substances, it is high in fat, high protein, low-fiber diet carcinogenic substances produced by many, the role of the large intestine for a long time, will inevitably lead to increased incidence of colon cancer.
Colorectal cancer prevention (2) to prevent and treat intestinal disorders. Such as various polyps, chronic colitis (including ulcerative colitis), schistosomiasis, and other chronic diseases. For intestinal polyps should be addressed early. Colorectal polyps were divided into five categories, namely, adenomatous polyps, metaplastic polyps, inflammatory polyps, hamartomatous polyps, and other so avoid the meat of which is true adenomatous polyps cancer, is a precancerous lesion of colorectal cancer, So when found to have adenomas in the large intestine, it should be treated, and the pathological examination of removed adenomas, benign adenoma stage wish to be removed to prevent colon cancer. Larger number of the large intestine adenoma or adenoma risk disease (familial polyposis), if not treated early, the vast majority will become a cancer, the prognosis is poor. In addition, aggressive treatment of habitual constipation should be to keep the stool.
Colorectal cancer prevention (3) high risk of colorectal cancer, such as men over the age of 40, familial multiple intestinal polyps in patients with ulcerative colitis patients with chronic schistosomiasis patients and people with a family history of colorectal cancer should be checked regularly guard against colorectal cancer and early warning symptoms, such as change in bowel habits, diarrhea, alternating constipation, stool or black stool, stool flat shape change.
