A clear understanding of the clinical causes of colorectal cancer

Understanding the causes of colorectal cancer can not only help people better prevent colorectal cancer, but also have great benefits for the treatment of colorectal cancer. So what are the causes of colorectal cancer? The following experts will introduce the causes of colorectal cancer .

In general, the common causes of bowel cancer are:

1) Age: As age increases, the time that various pathogenic factors stimulate the colon mucosa also increases, and most patients develop the disease after the age of 50. This is one of the common causes of colon cancer.

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 disease: It is also a common cause of bowel cancer. Certain bowel 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.

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 malignancy of about 25%; the malignancy rate of tubular adenomatous polyps is 1-5%.
