Colorectal cancer prevention

Colon cancer prevention 

Colon cancer is the third leading cause of death in the world. Despite great advances in the treatment of colon cancer, the 5-year survival rate of advanced colon cancer over the years has not changed much. Therefore, the significance of colon cancer prevention is increasingly important.

1primary prevention

(1) Dietary Interventions

Due to the complexity of dietary nutrient interactions, the type of diet is more important than the specific ingredients, and dietary interventions often do not work as a single factor. In addition, the occurrence and development of the tumor is a long process. Dietary intervention is also a behavioral intervention. Under the guidance of homologous theory of Chinese medicine, modern nutrition aids and co-carry out dietary intervention.

(2) chemoprevention

Chemoprevention is a new concept of tumor control proposed in recent years. It refers to the prevention of tumor development by using one or more natural or synthetic chemical agents, ie, chemopreventive agents (CPA). In a broad sense dietary intervention is also a chemical prophylaxis because it can be achieved by changing dietary habits and can therefore also be considered as a behavioral intervention. Chemopreventive agents can prevent the occurrence of tumors and suppress their development by inhibiting and blocking the formation, absorption and action of carcinogens.

(3) treatment of precancerous lesions

It is generally believed that precancerous lesions of colon cancer include adenomatous polyps, ulcerative colitis and Crohn’s disease, etc., and adenomas are particularly closely related to colon cancer.

2Secondary prevention

High-risk colon cancer screening, in order to find asymptomatic patients with precancerous tumors. To achieve early diagnosis and early treatment to improve the survival rate of patients and reduce population mortality. As screening can not only detect early colon cancer, colon cancer can also be found in precancerous lesions

This is because long-term sit-in at the desk, the human intestinal peristalsis slowed down, the harmful components in the stool, including carcinogens, stranded in the colon and stimulate the intestinal mucosa; plus semen peritoneal, pelvic, waist blood Poor circulation can lead to a decrease in intestinal immune barrier function – all of which increase the risk of colon cancer. Therefore, some experts call this type of colon cancer sitting in front of the desk a “desk work cancer.” Experts said that “weekly exercise can effectively prevent colorectal cancer.”

Cancer Prevention: Starting from “eating”

Old Zhou opened an advertising company. Business start-ups, customers join, Old Week often a copy, with a bunch of young people full input, completely attend to seriously eat a meal.

High-fat, high-protein, low-fiber foods have always led to high levels of many cancers. Fruits and vegetables are the “green barrier” to prevent this kind of cancer. Lack of diet taking, excrement in the intestine will stay longer, resulting in intestinal reabsorption of waste, causing carcinogens in the stool to stimulate the intestinal wall for a long time. The fruits and vegetables provided by vegetables and fruits known as the intestinal cleaner, it is like a small brush to promote intestinal peristalsis, cleaning the intestinal waste and waste, reducing the intestinal carcinogens residence time, thereby reducing Risk of colorectal cancer. The American Association for the Prevention of Cancer recommends daily intake of 30 to 40 grams of dietary fiber; the standard daily intake of Japanese under 70 is 19 to 27 grams per day; our recommended standard is 30 grams of daily dietary fiber.
