Analysis of common causes of colorectal tumors

In recent years, there are many patients suffering from colorectal tumors. Therefore, the cause of colorectal tumors has become one of the issues that people pay close attention to. So, what exactly causes colorectal tumors?

Regarding the causes of colorectal cancer, relevant experts introduce as follows:

1. Genetic factors: The risk of colorectal cancer in the general population is 1/50. The risk of first-generation relatives of the patient developing cancer increases three times to 1/17. If two first-generation relatives develop cancer, the risk rises to 1/6. This family heredity is more common in colon cancer than in rectal cancer.

2. Dietary factors It is generally believed that a diet high in animal protein, high in fat and low in fiber is the cause of colorectal tumors. Eating more fat will increase bile secretion, resulting in more bile acid decomposition products, and the activity of anaerobic enzymes in the intestine will also increase, which will increase the formation of carcinogens and pro-carcinogens in the intestine and lead to the occurrence of colorectal tumors.

3. Abnormal colorectal diseases It is estimated that 3% to 5% of ulcerative colitis patients will develop colorectal tumors. 12.5% ​​of ulcerative colitis patients will develop cancer after 20 years, and 40% after 30 years. Some people believe that 15% to 40% of colon cancer originates from multiple colon polyps, and the precancerous course is 5 to 20 years.

4. Parasitic diseases. Data from my country show that 10.8% to 14.5% of patients with advanced schistosomiasis are complicated by colorectal cancer. In Egypt, 12.5% ​​to 17.34% of colorectal tumors are complicated by schistosomiasis mansoni, which is one of the causes of colorectal tumors.

Do you understand the causes of colorectal cancer through the above introduction? Relevant experts point out that environmental factors are related to colorectal cancer. Colorectal cancer is more common in molybdenum-deficient areas and in asbestos workers.
