Can colorectal cancer be contagious to humans?

Is colorectal cancer contagious? In recent years, with the continuous development of the economy, people's pace of life has become faster and faster, and irregular eating habits and lifestyles have led to a high incidence of colorectal cancer. Colorectal cancer is a common malignant tumor that causes great harm to patients. So, is colorectal cancer contagious?

Is colorectal cancer contagious? I can tell you for sure that colorectal cancer is not contagious, so it will not be transmitted to anyone. The main causes of colorectal cancer include benign adenomas in the colorectal turning into cancer, too much fat and refined carbohydrates in the diet, lack of refined fiber, poor bowel movements, and carcinogens that remain in the intestine for a long time, irritating the intestinal mucosa and causing cancer.

Colorectal cancer has an insidious onset, often without obvious clinical manifestations in the early stages, and develops slowly. The long-term efficacy is better than other digestive tract malignancies, and the prognosis is relatively good, but the incidence of colorectal cancer is high and has been rising year by year. There are no symptoms in the early stages, or the symptoms are not obvious, only discomfort, indigestion, occult blood in the stool, etc. As the cancer develops, symptoms gradually appear, manifested as changes in bowel habits, abdominal pain, blood in the stool, abdominal mass, intestinal obstruction, etc., with or without systemic symptoms such as anemia, fever and weight loss.

Studies have shown that among various environmental factors, diet is the most important. The incidence of colorectal cancer is positively correlated with the high fat consumption in food. In addition, it may also be related to the lack of trace elements and changes in lifestyle habits. Dietary habits and nutritional methods are also closely related to colorectal tumors.

The high incidence areas are economically developed, and people eat too much meat, fat, refined carbohydrates, etc., and lack refined fiber, which is not conducive to defecation. Food residues are retained in the intestine for a long time, and carcinogens accumulate in them, which will stimulate the intestinal mucosa for a long time and cause lesions. Although colorectal cancer has a certain genetic tendency, the vast majority of sporadic colorectal cancers are closely related to environmental factors, especially dietary factors. Intervention in diet can reduce the incidence of colorectal cancer.
