Four causes of colorectal cancer that need attention

Intestinal cancer is a malignant tumor with a high incidence rate. People who like to eat and drink a lot are prone to intestinal cancer, 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. Age: As age increases, the time that various pathogenic factors stimulate the colon mucosa also increases. Most patients with colorectal cancer develop the disease after the age of 50. This is one of the causes of colorectal cancer.

2. 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 colorectal cancer, with a chance of malignancy of about 25%; the malignancy rate of tubular adenomatous polyps is 1-5%.

3. Sexual history: Certain colon diseases such as Crohn's disease or ulcerative colitis may increase the chance of developing colon cancer. Their risk of colon cancer is 30 times that of ordinary people. Therefore, this is also a cause of colon cancer.

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

The above are the common causes of colorectal cancer. I hope it will alert everyone. To prevent this disease, we should maintain good living habits. I wish you all good health.
