What are the causes of rectal cancer

summary

Once the occurrence of rectal cancer, a terrible malignant tumor disease, makes patients suffer too much pain and suffering, and the occurrence of the disease also has a relatively high mortality rate. When suffering from rectal cancer, we should actively take symptomatic treatment measures to understand the factors of rectal cancer?

What are the causes of rectal cancer

1. Rectal adenoma canceration: some adenomatous polyps can have canceration, among which villous adenoma has the highest canceration rate. In addition, hereditary familial multiple adenomas are generally regarded as precancerous lesions. Data show that the disease usually occurs after the age of 30, but there are also cancer cases before the age of 20.

2. There is an obvious relationship between diet structure and colorectal cancer. The incidence rate of colorectal cancer in high fat, high protein and low fiber diet was significantly higher than that in other areas. At present, although the mechanism of high-fat, high protein, low cellulose diet promoting colorectal cancer is not fully clear, it is generally believed that it may be related to the following factors:

3. Genetics: Recently, some scholars have studied the relationship between tumor suppressor genes and the occurrence of rectal cancer, and found that the susceptibility and pathogenesis of rectal cancer are related to genetic factors. In addition, there are many reports about familial aggregation tendency of rectal cancer at home and abroad, suggesting that genetic factors play an important role in the occurrence of rectal cancer.
