Experts analyze factors related to the causes of colorectal cancer

Intestinal cancer is a malignant tumor with a relatively complex etiology. There are many known causes of intestinal cancer, which is very helpful for the treatment of intestinal cancer. What are the common causes of intestinal cancer ? Let's talk about the common causes of intestinal 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: This 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%.

5) Genetic background: Familial adenomatous polyposis and hereditary non-polyposis colorectal cancer are common causes of colorectal cancer. Patients with this disease not only have a significantly increased risk of developing the disease, but also develop the disease at a younger age.

The above is an introduction to the common causes of colorectal cancer. I hope it will be helpful to you. For more questions about the causes of colorectal cancer, you can consult our online experts, who will answer them in detail.
