Where is rectal cancer

First, rectal cancer refers to the cancer from the dentate line to the junction of rectum and sigmoid colon, which is one of the most common malignant tumors in the digestive tract. 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.

Second: 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, which is a difficult problem in the operation, and also a disease with the most controversial surgical methods. The median age of rectal cancer in China is about 45 years old. The incidence rate of young people is increasing.

The incidence rate incidence rate of incidence of colorectal cancer is third. The incidence rate of colorectal cancer is increasing year by year.
