What factors are mainly responsible for the increasing incidence of colorectal cancer?

Colorectal cancer is one of the tumor diseases in the intestinal tract. The occurrence of colorectal cancer affects the peristaltic function of the large intestine. So, what is the cause of colorectal cancer ? Let's learn about it from the following article.

1. Genetic factors: There are reports of "family-based colorectal cancer" both at home and abroad. The number of blood relatives of colorectal cancer patients who died of the disease is significantly higher than that of the general population. Recently, some scholars have studied the relationship between tumor suppressor genes and colorectal cancer and found that the cause and pathogenesis of colorectal cancer are related to genetic factors.

2. Colon adenoma: According to autopsy data from various places, the incidence of colon adenoma is quite consistent with that of colon cancer. According to statistics, the incidence of colon cancer in patients with one adenoma is 5 times higher than that of patients without adenoma, and the incidence of patients with multiple adenomas is 1 times higher than that of patients with a single adenoma. Therefore, this is also one of the causes of colon cancer.

3. Chronic colon inflammation: The risk of colorectal cancer in patients with chronic ulcerative colitis is 4 to 20 times higher than that in normal people. The risk of malignant transformation in patients with hemorrhagic ulcerative colitis is even greater. For patients with a disease course of more than 10 years, 50% will develop colorectal cancer.

The above factors are the causes of colorectal cancer. I hope you can better understand how colorectal cancer is formed. They are for reference only. If you have other questions about colorectal cancer, you can contact our online experts to answer your questions.
