Can colon cancer patients be contagious?

Is colon cancer contagious? Do you know that colon cancer is contagious? Do you know that colon cancer is contagious? Colon cancer is not contagious. Colon cancer is one of the common malignant tumors, and the highest incidence rate is in the 40-50 age group. According to the world epidemiological survey, the incidence rate of colon cancer is highest in North America, Western Europe, Australia, New Zealand and other places, ranking first and second among visceral tumors, but the incidence rate is very low in Asia, Africa, Latin America and other places. Below, the experts will introduce you in detail;

Colon cancer is one of the common malignant tumors of the digestive tract. Its incidence rate is second only to gastric cancer and esophageal cancer. It is more common in people over 50 years old, and more common in men than women, with a male-to-female ratio of 2:1. The cause of colon cancer is still unclear, and it is mainly related to environmental factors, genetic factors, precancerous diseases, and other diseases.

1. Environmental factors The incidence of colon cancer is related to lifestyle and diet, especially diet. High-fat diet and insufficient dietary fiber are the main causes of the disease. High-fat diet, especially food containing saturated fatty acids, can promote the synthesis of cholesterol and bile acid in the liver, increase the amount of cholesterol entering the intestinal cavity, and the colon bacteria convert it into cholesterol metabolites and hypocholic acid, which has a carcinogenic effect. The lack of unabsorbed cellulose in food causes feces to stay in the intestine for a long time, which prolongs the action time of carcinogens in the feces on the intestinal wall and promotes the absorption of carcinogens by the intestine. The high fiber in food has the ability to absorb water, which can increase the amount of stool, reduce the concentration of carcinogens, shorten the residence time in the intestine, reduce the action time of intestinal carcinogens, and absorb harmful substances, promote excretion, thereby reducing the risk of colon cancer. Insufficient dietary fiber is one of the causes of colon cancer.

2. Genetic factors Genetic factors are one of the causes of colon cancer. Family history: If a first-degree relative has had colorectal cancer, the next generation is more likely to suffer from the disease than the general population. About 1/4 of new patients have a family history of colorectal cancer.

3. Inflammatory bowel disease Patients with ulcerative colitis have a much higher risk of developing colon cancer than the average person. This is more common in patients with a wide range of lesions and a long course of disease at a young age. Canceration often occurs in flat mucosa. In the process of the development of inflammatory proliferative lesions, polyps are often formed, which further develop into colon cancer; in Crohn's disease, those with colon and rectum involvement can also cause canceration. The chance of developing Crohn's disease or ulcerative colitis is 30 times that of an average person. 4. Schistosomiasis: There is a significant difference in the incidence and mortality of colon cancer in schistosomiasis-endemic areas and non-endemic areas. In the past, it was believed that patients with chronic schistosomiasis had chronic ulcers and inflammatory polyps in the colon mucosa due to the deposition of schistosomiasis eggs in the intestinal wall and the stimulation of toxins, which then caused canceration.
