Explore the causes of rectal cancer

In life, many people suffer from gastrointestinal diseases to varying degrees, and rectal cancer is one of them. When you have rectal cancer, it will cause great harm to the human body. So, what are the common causes of rectal cancer ? Next, let's learn about it from the following article.

1. Genetic factors: In the families of patients with rectal cancer, many have a family history of cancer and many digestive tract tumors. Due to the change of genes in normal cells, cancer patients inherit a susceptibility, and with some stimulating factors, tissue cells grow rapidly, which will develop into rectal cancer. Cell genetic genes mutate and become malignant cells with genetic characteristics, which manifests as a family history of cancer. Therefore, this is one of the causes of rectal cancer.

2. Adenoma canceration: This is also a common factor that leads to 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 rate of canceration. Among adenomas, there are hereditary familial adenomas, which are considered precursors of rectal cancer and usually occur after the age of 30.

3. 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 the transformation of rectal cancer. This is also one of the causes of rectal cancer.

The above is a detailed description of the factors that lead to rectal cancer. I hope it can help everyone understand the knowledge of rectal cancer in this regard and cure rectal cancer in time.
