The main causes of colon cancer

Colon cancer is a common digestive tract malignancy that occurs in the colon. The incidence rate is highest among middle-aged and elderly people. With the improvement of people's living standards and changes in dietary structure, the incidence rate is increasing year by year. So what are the causes of colon cancer ? The following is a detailed answer from relevant experts.

The cause of colon cancer is closely related to social development, lifestyle and dietary structure, and there are phenomena suggesting that there may be differences in environmental and genetic factors affecting the incidence of colon cancer in different parts and age groups. Environment (especially diet), genetics, physical activity, occupation, etc. are possible causes of colon cancer.

The cause of colon cancer also has genetic factors; it is estimated that genetic factors may play an important role in at least 20% to 30% of colon cancer patients, of which 1% are patients with familial polyposis and 5% are patients with hereditary non-polyposis colon cancer syndrome. 80% to 100% of patients with hereditary familial polyposis may develop malignant tumors after the age of 59. In addition, the majority of patients with familial polyposis develop left-sided colon cancer, while patients with hereditary non-polyposis syndrome mostly suffer from right-sided colon cancer.

Dietary factors: Tea: Tea polyphenols are a strong antioxidant that can inhibit the carcinogenic effect of carcinogens. Vitamins: Case-control studies have shown that carotene, vitamin B2, vitamin C, and vitamin E are all associated with a reduced relative risk of colon cancer, and the relationship is dose-response. Vitamin D and calcium have a protective effect. Onions and garlic: The protective effect of onion and garlic foods on the body has been widely recognized, and experiments have repeatedly confirmed that this type of food can inhibit tumor growth. This is one of the causes of colon cancer.

Trace elements and minerals, including selenium and potassium, are speculated to be associated with a lower risk of colon cancer. However, some believe that these factors may only be concomitant factors and do not directly affect the risk of colon cancer in the population. Some epidemiological studies also suggest that calcium intake can play a protective role in preventing the occurrence of colon cancer.

A diet high in fat, protein, and fiber will increase the incidence of colon cancer. Salt and pickled foods: The process of pickling food is related to carcinogens, and high salt intake may be a concomitant condition.

Causes of colon cancer: occupation. Insulating asbestos production workers are more common among colon cancer patients, and animal experiments have confirmed that swallowed asbestos fibers can penetrate the intestinal mucosa. In addition, metal industry, cotton yarn or textile industry and leather manufacturing industry. It has been confirmed that acrylonitrile, a compound often used in the production process of plastics, synthetic fibers and rubber, can induce stomach, central nervous system and breast tumors, and textile workers who are exposed to this substance have a higher incidence of lung cancer and colon cancer. Despite this, colon cancer is generally not considered an occupational disease. The risk of colon cancer for people who sit for a long time or often is 1.4 times that of some occupations with greater physical activity, and is more closely related to cecal cancer. Moderate-intensity physical activity plays a protective role in preventing colon cancer (especially colon cancer).

Causes of colon cancer: Basic diseases such as intestinal inflammation and polyps: Schistosomiasis: Cholecystectomy: In recent years, there have been more than 20 papers in my country discussing the relationship between cholecystectomy and colon cancer. Some of these studies have shown that cholecystectomy can increase the risk of colon cancer, especially proximal colon cancer.

The above is an introduction to the causes of colon cancer. Colon cancer patients can try to change their high-fat, high-protein, low-fiber diet and eat more vegetables and fruits. If you want to know more about colon cancer, please consult online experts.
