How does rectum cancer form

summary

A few days ago when I was eating, my father-in-law suddenly had a part of the intestinal tract pain, the pain was very severe, so we quickly sent him to the hospital, to the hospital for examination, the doctor said it was rectal cancer, we were very shocked, because my father-in-law had been in good health before, do not know what the cause of rectal cancer. Now let's take a look at how rectal cancer forms.

How does rectum cancer form

First, environmental factors. Studies have shown that in all kinds of environmental factors, dietary factors are most important. The incidence rate of rectal cancer is positively related to the high fat consumption in food. In addition, it may be related to the lack of trace elements and the change of living habits.

Second, genetic factors. It has been reported that rectal cancer is familial at home and abroad. The number of blood relatives of rectal cancer patients who died of this disease is significantly higher than that of ordinary people. Some colorectal adenomas, such as multiple familial adenomas, are autosomal dominant genetic diseases. The prevalence rate in the family can reach 50%. Without treatment, rectal cancer may occur after the age of 10. 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.

Third: colorectal adenoma. According to the autopsy materials, the incidence of colorectal adenoma is quite consistent with rectal cancer. According to statistics, the incidence of rectal cancer in patients with one adenoma is 5 times higher than that in patients without adenoma, and that in patients with multiple adenomas is 1 times higher than that in patients with single adenoma.
