What is the cause of rectal cancer

Why do so many people still suffer from rectal cancer when living conditions are better now? What causes rectal cancer? What factors are related to the disease? At present, there is no clear answer, but the disease may be related to genetics and holding back urine and feces, and it may also be related to low cholesterol. It can be seen that the causes of the disease are still relatively broad. So what exactly are the causes of rectal cancer? Let's take a closer look below.

Inflammatory bowel disease

Inflammatory bowel disease is the main cause of rectal cancer. For example, Crohn's disease and ulcerative colitis cause intestinal mucosal damage, ulcer repair and proliferation, which leads to canceration in the process of granulation tissue formation. If schistosomiasis eggs are deposited in the rectal mucosa of the human body, chronic inflammation can occur, leading to canceration. This is a common cause of rectal cancer.

Dietary factors

The diet in Western countries is mostly high in fat, high in protein and low in fiber, and they are also high-incidence areas for colorectal cancer. It can be seen that the cause of colorectal cancer is related to diet. The incidence of colorectal cancer is high in Western countries. In contrast, the Banti tribe in South Africa consumes rough food with low fiber and fat, so the incidence of colorectal cancer is low. People who immigrate to areas with high incidence of colorectal cancer have a change in their diet structure and an increase in the incidence.

Genetic factors

Many patients have this disease clustering in their families, and many patients have digestive tract tumors. Because they have inherited the susceptibility gene for this disease, the normal cell gene changes, and the patients who have inherited a susceptibility encounter some stimulating factors of this disease, which accelerates the rapid growth of tissue cells and eventually develops into cancer. Due to the mutation of cell genetic genes, the genetic characteristics of malignant cell cancer tumors are changed.

Warm reminder: The increasing number of patients with rectal cancer may also be related to the lack of understanding of the disease, the failure to detect symptoms in time, and the delay in treatment of the disease, which in turn leads to the aggravation of the patient's condition and endangers the patient's health. Therefore, understanding the cause of rectal cancer is also helpful for preventing rectal cancer. Specific biological immunotherapy is highly safe, has few toxic side effects, and has no serious adverse reactions; it has a broad spectrum of killing tumor cells and viruses, and is still sensitive to multi-drug resistant tumor cells; it can alleviate symptoms, improve the quality of life of patients, and prolong the life of patients.
