Why do people get colorectal cancer?

In clinical practice, rectal cancer is also a type of intestinal cancer. Many people have lost their lives because they did not get timely treatment for intestinal cancer. So, what are the causes of rectal cancer ? Let's learn about it from the following article.

1. Diet structure: Epidemiological studies have shown that the occurrence of colorectal cancer is significantly related to economic conditions and dietary structure. The incidence rate is significantly higher in economically developed areas, areas and groups where the diet has a high proportion of animal fat and protein and a low fiber content. The cause of dietary structure and colorectal cancer is generally believed to be related to factors such as the metabolites of animal fat, bacterial decomposition products, and slowed intestinal peristalsis and increased intestinal toxin absorption due to a low-fiber diet.

2. Colon polyps : This is also one of the causes of rectal cancer. According to the histological structure of the polyps, adenomatous polyps can be divided into villous polyps and tubular polyps; according to the number of colon polyps and their heredity, adenomatous polyps can be divided into single, multiple and familial hereditary polyposis, which can lead to the occurrence of rectal cancer.

3. Chronic colorectal inflammation: Chronic ulcerative colitis and granulomas caused by chronic schistosomiasis are directly related to the occurrence of colorectal cancer. The longer the course of the disease, the higher the possibility of colorectal cancer. The incidence of colorectal cancer in patients with ulcerative colitis for more than 20 years is about 20-40%. Therefore, these are important factors that lead to rectal cancer.

The above is a detailed description of the causes of rectal cancer. I hope it can help everyone understand the knowledge of colorectal cancer and cure colorectal cancer in time. If you have other questions about colorectal cancer, you can contact our online experts to answer your questions.
