What is the cause of rectal cancer

Rectal cancer is a very troublesome problem for many people. Because of rectal cancer, some patients suffer great pain every day. After the occurrence of rectal cancer, patients also need to spend a lot of money on treatment. Therefore, everyone should pay attention to the cause of rectal cancer and learn how to prevent this disease. Let's take a look at the cause!

The main causes of colorectal cancer are:
1. If you have the habit of holding back your urination and defecation, it is easy to cause this disease, because human urine contains carcinogens, which can stimulate the bladder epithelium and cause cancer. It will also increase harmful substances in feces, such as cholesterol metabolites, hydrogen sulfide, and secondary bile acid and other carcinogens. If the mucosa is often stimulated by these carcinogens, it may lead to the occurrence of this disease.
2. Among some colorectal cancer patients, nearly 5% of them have a significant family history of cancer. It can be seen that the disease is related to heredity. If there are patients with rectal diseases in the family, they should pay attention to preventing the disease and reduce the risk of the disease.
3. Experts say that low cholesterol can increase the risk of colorectal cancer. If the serum cholesterol is less than 110mg/dl, the likelihood of developing the disease is three times higher than that of an average person. Therefore, low cholesterol is also a major factor leading to the disease. In life, we should try to maintain a balanced level of good cholesterol to reduce the chance of developing the disease.
