Bad habits in life can lead to the occurrence of rectal cancer

Rectal cancer is a major tumor disease that many people are prone to. The occurrence of rectal cancer is mainly caused by improper diet. So, what factors are the causes of rectal cancer ? Next, let's learn about it from the following article.

1. Chronic rectal inflammation is one of the causes of rectal cancer. For example, 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%.

2. Diet and carcinogens also play a certain role in colorectal cancer. 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. Dietary structure is related to the cause of colorectal cancer. It is generally believed that it may be related to factors such as the metabolites of animal fat, bacterial decomposition products, and the slowing of intestinal peristalsis and increased intestinal toxin absorption due to a low-fiber diet.

3. Genetic factors can also easily lead to the occurrence of rectal cancer. In addition to patients with colorectal cancer caused by familial polyposis or malignant transformation of ulcerative colitis, among other colorectal cancer patients, about 5-10% of patients have a clear family history of tumors, collectively referred to as hereditary non-familial polyposis colorectal cancer.

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