What are the brief introductions to rectal cancer?

The health of our body is directly linked to our daily living habits. Everyone can truly understand this. Just like the occurrence of rectal cancer, can everyone realize what aspects of our lives are related to the occurrence of this disease? If you want to know more about this issue, let’s take a look at the expert’s introduction to rectal cancer.

1. Colon polyps: Colon polyps can be divided into adenomatous polyps, hyperplastic polyps, inflammatory polyps and hamartomatous polyps. 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.
2. Diet structure: Epidemiological studies have shown that the cause 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 exact mechanism of the relationship between dietary structure and the cause of colorectal cancer is not yet fully understood. 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. Chronic inflammation of rectal cancer: Chronic ulcerative colitis and granulomas formed by chronic schistosomiasis are directly related to the cause of rectal cancer. The longer the course of the disease, the higher the possibility of rectal cancer. The incidence of rectal cancer in patients with ulcerative colitis for more than 20 years is about 20% to 40%.
4. Genetic factors: This is one of the causes of rectal cancer. In addition to rectal cancer patients caused by familial polyposis or malignant transformation of ulcerative colitis, about 5% to 10% of other rectal cancer patients have a clear family history of tumors, collectively referred to as hereditary non-familial polyposis rectal cancer.
The above is the relevant knowledge about rectal cancer. Don’t be too nervous after learning that you have this disease. As long as we can actively cooperate with the doctor’s treatment, we must go to the hospital for relevant examinations when there are any changes in our body to ensure our physical condition. I hope all patients and friends can truly understand this.
