Common causes of colon cancer

What are the common causes of colon cancer? I believe many people have this question. Many patients suffer from colon cancer but do not know the cause of their disease, which brings some difficulties to their treatment. Let us follow the experts to understand the causes of colon cancer .

1. Diet is one of the causes of colon cancer. Epidemiological studies have shown that 70% to 90% of tumors are related to environmental factors and lifestyle, and 40% to 60% of environmental factors are related to diet and nutrition to a certain extent. Therefore, dietary factors are considered to be extremely important factors in the development of tumors.

2. Occupational factors and physical activity are also causes of colon cancer. Insulation 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 a compound often used in the production process of plastics, synthetic fibers and rubber, acrylonitrile, 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.

3. 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. This is also the cause of colon cancer.
