Analyzing the causes of colorectal cancer that everyone needs to pay attention to

Intestinal cancer is a very common intestinal malignancy, which can cause patients to have symptoms such as changes in bowel habits and a feeling of incomplete defecation. In severe cases, patients may experience weight loss, fatigue, and loss of appetite, which is very harmful to patients. 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. 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. This is a common cause of colorectal cancer.

2. Family history: This is also a common cause of colorectal cancer. 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].

3. 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 malignant chance of about 25%; tubular adenomatous polyps have a malignant rate of 1-5%; this cause of colorectal cancer is relatively common.

The above analysis is about the common causes of colorectal cancer. I believe everyone should have some understanding of this. If you have any questions, you can contact our online experts, who will give detailed answers based on the patient's specific situation.
