What risk factors increase the incidence of colon cancer?

What risk factors increase the incidence of colon cancer? I believe many people have this question. There are many factors in life that increase the incidence, but some people have not paid attention to them. Let us follow the experts to learn about the risk factors that affect colon cancer .

1. Age of onset: most patients develop the disease after the age of 50.

2. 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. This is one of the risk factors affecting colon cancer.

3. 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. This is also a common risk factor for colon cancer.

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

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. This is one of the risk factors affecting colon cancer.
