Where to start surgery for rectal cancer

Patients will be surrounded by various diseases in life, especially if they suffer from rectal cancer, which will cause great harm. This type of disease is not easy to detect. Patients will not find its symptoms until the late stage of the disease. When they find discomfort in life, patients should actively do a check-up. Let's see how to check for rectal cancer!

1. Digital rectal examination

Rectal cancer patients, especially lower rectal cancer, can be detected very early by digital examination. However, some doctors do not perform this routine examination on patients suspected of rectal cancer, which delays the diagnosis and treatment of patients. In fact, this diagnostic method is simple, feasible and effective. Rectal digital examination can also help determine the degree of infiltration and size of the palpable mass, or whether the mass is fixed, whether there is an implanted mass outside the intestinal wall or in the pelvic cavity, etc.

2. Proctoscopy or sigmoidoscopy

Another clinical examination method for rectal cancer diagnosis is colonoscopy, which is a method of examination after rectal digital examination. The chief physician makes the diagnosis by observing the upper and lower edges of the cancerous mass, the distance from the anal edge, and the shape. The mass tissue is examined by pathological section to determine the nature of the mass and the degree of differentiation of the mass. The upper part of the cancer and the rectum cannot be touched by fingers, so sigmoidoscopy is used.

3. Barium enema and fiber colonoscopy

Since fiber colonoscopy and barium enema are not very helpful in diagnosing rectal cancer, they are not listed as routine examinations. They are only used to exclude colon and multiple tumors, so they are not widely used. Rectal cancer patients can first undergo a rectal digital examination and then undergo corresponding examinations.

Patients are aware of the examinations that need to be done for rectal cancer, and they need to take good care of themselves in life. Only when the care is done well can the disease of rectal cancer be cured. Patients should have confidence in life, do examinations and treatments in time, and pay attention to the disease when it is discovered. A good mentality is very important for patients.
