Analyzing the causes of colon cancer in patients

Colon cancer is a malignant tumor that endangers the health and life of patients. With the improvement of living standards, the incidence of colon cancer is getting higher and higher. So, what are the causes of colon cancer? Let us introduce it to you in detail.

Colon cancer is a common malignant tumor in the intestine, with an incidence rate second only to gastric cancer and esophageal cancer. There are almost no benign ones, and it is the most common part of colorectal cancer. The highest incidence rate is in the 40-50 age group. In my country, its incidence rate and mortality rate are lower than those of common malignant tumors such as gastric cancer, esophageal cancer, and lung cancer.

1. Family history: If a person's first-degree relatives, such as parents, have had colorectal cancer, his risk of developing the disease in his lifetime is 8 times higher than that of the general population. About a quarter of new patients have a family history of colorectal cancer;

2. Genetic characteristics: Some familial tumor syndromes, such as hereditary non-polyposis colon cancer, can significantly increase the chance of developing colorectal tumors, and the onset time is younger.

3. Age of onset is one of the causes of colon cancer. Most patients develop the disease after the age of 50. Middle-aged and elderly people over the age of 50 must pay more attention to changes in their bodies. Annual physical examinations are particularly important.

4. History of colon disease: Certain colon diseases such as Crohn's disease or ulcerative colitis may increase the chance of developing colorectal cancer. Their risk of colon cancer is 30 times that of ordinary people;

5. Polyps: Most colorectal tumors develop from small preneoplastic lesions, which are called polyps. Among them, villous adenomatous polyps are more likely to develop into tumors, with a malignant chance of about 25%; tubular adenomatous polyps have a malignant rate of 1-5%.

After reading the above introduction, I believe everyone has a certain understanding of the causes of colon tumors. I would like to remind everyone to take preventive measures in life to prevent the occurrence of colon tumors.
