What does rectal cancer mean

1. Rectal cancer refers to the cancer from the dentate line to the junction of rectum and sigmoid colon. It is one of the most common malignant tumors in digestive tract.

2. The location of rectal cancer is low, so it is easy to be diagnosed by digital rectal examination and sigmoidoscopy. However, because of its deep location in the pelvic cavity and complex anatomical relationship, the operation is not easy to complete and the recurrence rate is high.

3. The middle and lower rectal cancer is close to the anal sphincter, so it is difficult to preserve the anus and its function during the operation. It is a difficult problem in the operation, and it is also the most controversial disease in the operation method.

matters needing attention

The etiology of rectal cancer is still not very clear, its incidence is related to social environment, eating habits, genetic factors and so on. At present, it is generally recognized that excessive intake of fat and protein and insufficient intake of food fiber are the risk factors of rectal cancer. So we should pay attention to eat less of these foods.
