What are the main causes of colon cancer?

Many people who have colon cancer are worried that they will not be cured. Because colon cancer is also a type of cancer and a malignant tumor. Therefore, to cure colon cancer in time, we should first find out the factors that cause colon cancer . Now, let's learn about colon cancer knowledge in this regard.

1. Age of onset: Most patients with colon cancer develop the disease after the age of 50. People over the age of 50 must pay more attention to changes in their bodies, and annual physical examinations are particularly important. Therefore, this is also an unavoidable cause of colon cancer.

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

3. Polyps: This is also one of the causes of colon cancer. Most colon cancers develop from small precancerous lesions, which are called polyps. Among them, villous adenomatous polyps are more likely to develop into cancer. The chance of malignant transformation of colon cancer is about 25%.

4. Family history: If a person's first-degree relatives, such as parents, have had colon cancer, his risk of developing colon cancer in his lifetime is 8 times higher than that of the general population. About a quarter of new patients have a family history of colon cancer. Therefore, this is also an important factor in the cause of colon cancer.

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

The above is a detailed description of the causes of colon cancer.
