Colorectal cancer, commonly known as large bowel cancer, is a common tumor of the large intestine. It is often misdiagnosed due to the long - term occurrence of hemorrhoids. Therefore, early diagnosis is very important.

One should go to the proctology department of a hospital for an anoscopy. After confirmation of the diagnosis, an appropriate treatment method should be selected, which generally includes various surgical approaches.

Once large bowel cancer is diagnosed, radical surgery is the most effective treatment. The effectiveness of surgical treatment is closely related to how early the cancer is detected. For localized large bowel cancer, the five - year survival rate after radical surgery can reach over 90%.

There are two types of surgical treatment methods:1. Traditional open - abdomen surgery2. Minimally invasive surgery

Open - abdomen surgery has a relatively long incision, large trauma, and slow recovery. Minimally invasive surgery, taking advantage of laparoscopic surgery, provides patients with an additional treatment option, bringing good news to them.
