What Is the Connection Between Polyps and Cancer?

Intestinal polyps is a common intestinal disease. It is a raised lesion protruding from the surface of the intestinal mucosa to the intestinal cavity. The symptoms are blood around the stool and bleeding after the stool. If it is an inflammatory hyperplastic polyp, its pathological nature is benign. If intestinal polyps are accompanied by atypical hyperplasia, it is easy to become cancerous.

1. Pathological changes:

It is generally believed that polyps are the early stage of canceration. From a pathological point of view, adenomas have a tendency to malignant changes.

Polyposis can affect the entire large intestine with a high degree of malignancy, accounting for about 60%.

2. Polyp size, adenocarcinoma

Chronic inflammation stimulation: Long-term chronic inflammation may be the cause of anorectal malignancy. Such as chronic bacterial infection, amoebic dysentery, chronic non-specific colitis, diverticulitis, hemorrhoids, anal fistula, anal fissure, suppurative sweat glanditis, folliculitis and other long-term stimulation of the anal skin can also cause malignant changes.

Malignant benign tumors: rectal familial polyposis, rectal adenoma, papilloma, etc., under certain conditions, can also lead to malignant lesions.

caused by sexually transmitted diseases: unclean sexual intercourse, causing incurable diseases or papillary fibroids in the anus, long-term frictional stimulation can cause malignant changes.

Dietary factors: High-fat, high-protein, and low-fiber diets are related to the incidence of rectal malignancy. This is because high-fat foods can increase bile secretion and promote the growth of intestinal bacteria, while bile alcohol and bile salts can form unsaturated cholesterol under the action of anaerobic bacteria, such as increased deoxycholic acid and lithocholic acid, which are two types of carcinogens. Increased number of substances, promote the incidence of rectal malignancy.
