Several common causes of rectal cancer

Rectal cancer is also a type of cancer. Rectal cancer mainly occurs in the intestine. So, do you know what factors may cause rectal cancer? Next, let's explore the causes of rectal cancer from the following article.

1. Adenoma canceration: This is one of the common causes of rectal cancer. Tubular polyps can become cancerous. Adenomas can be divided into three types: tubular adenomas, villous adenomas, and mixed adenomas. Tubular adenomas have a high incidence rate, and villous adenomas have a high canceration rate. Among adenomas, there are hereditary familial adenomas, which are considered precancerous lesions. Generally, rectal cancer will occur after the age of 30, but there are also cases of rectal cancer before the age of 20.

2. The cause of rectal cancer is also related to inflammatory bowel disease. Ulcerative colitis and Crohn's disease are caused by the destruction of intestinal mucosa, the proliferation of ulcer repair, and the formation of granulation tissue, which leads to cancer. Schistosomiasis eggs are deposited in the rectal mucosa, and chronic inflammation stimulates cancer, leading to the appearance of rectal cancer.

3. Others: such as immune deficiency, genetic factors, viral infection, and the effects of gastrectomy and cholecystectomy can also lead to the occurrence of rectal cancer. Therefore, this is also a factor that leads to the cause of rectal cancer.
