What are the risk factors for colorectal cancer

Intestinal cancer is one of the malignant tumors of the gastrointestinal tract, which brings great pain to people. Although the exact cause of colorectal cancer is still unclear, clinical findings show that the following factors can greatly increase the risk of colorectal cancer. They are related to the following factors, and I hope they can help you.

1) Age: As age increases, the time that various pathogenic factors stimulate the colon mucosa also increases. Most patients develop the disease after the age of 50.

2) Family history: If a person's first-degree family member, such as a parent, has had colorectal cancer, his risk of developing the disease in his lifetime is 8 times higher than that of the general population [If one of your direct family members (parents, siblings or children) develops colorectal cancer before the age of 50, or if two or more people in your paternal or maternal family have colorectal cancer, then you have a family history of colorectal cancer]. About 1/4 of new patients have a family history of colorectal cancer;

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

4) History of colorectal 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 chance of malignant transformation of about 25%; tubular adenomatous polyps have a malignant transformation rate of 1-5%;

5) Genetic background: Familial adenomatous polyposis and hereditary non-polyposis colorectal cancer are caused by mutations in the corresponding genes. These patients not only have a significantly increased risk of developing the disease, but also develop it at a younger age.
