The incidence of colorectal cancer keeps rising

White collars usually face heavy mental stress and have unreasonable eating habits of life and social intercourse. They are one of the vulnerable groups to colorectal cancer. The occurrence of colorectal cancer is a multifactor and multistage process. It is the body's result of internal and external cause interaction. Epidemiological studies have shown that environmental factors accounted for about 80% of the attributable risk of colorectal cancer, mainly associated with high fat, high heat, low fiber diet and lack of physical activity. 20% of colorectal cancer is associated with genetic factors.

Experts say that in the daily diet, one should eat more food which are high in protein and vitamin content and low in fat content. Fatty diet can improve intestinal bile acid concentration. High concentration of bile acid can induce cancer. One should eat more fish, poultry, lean meat, low-fat dairy products instead of fatty meat. Eat more boiled, steamed foods instead of fried food. Eat more fresh vegetables and fruits, especially green and yellow vegetables that are rich in vitamin A and vitamin C. Diet should not be too fine, appropriately eat some coarse fiber can promote bowel movements, reduce the duration carcinogens stay in the intestines.

Experts special remind us to eat less pickled or smoked food such as sausage, ham, bacon, salted fish, or fried foods. Preserved food contains carcinogenic nitrosamine compounds which are carcinogenic. Supplementing moderate amount of vitamin D and calcium can helps discharge the insoluble wastes outside the intestines.

The prevention and treatment of colorectal cancer requires healthy living habits. One should give up smoking. In the process of tobacco combustion, there can produce a large amount of toxic and harmful substances which can induce the occurrence of colorectal cancer, lung cancer and other malignant tumors.

For office workers, prevention and treatment of colorectal cancer calls for prevention and treatment of constipation. If the retention time of the wastes in the intestines is too long, the toxins (amines, phenols, ammonia, chemical carcinogens, such as azobenzene indole, methyl indole, hydrogen sulfide and other toxic products)can be developed into cancers.
