Rectal cancer is easy to be misdiagnosed, so the diagnosis of rectal cancer is very important. If the patient has symptoms of bleeding in the stool, it must be taken seriously and the harm of rectal cancer must not be ignored. So, what are the common methods for diagnosing rectal cancer? Let's ask the experts to tell us in detail about the diagnosis of rectal cancer.

The main methods for diagnosing rectal cancer are:

About 90% of rectal cancers, especially those in the lower rectum, can be detected by digital rectal examination alone. However, some doctors still do not perform this routine examination on patients suspected of rectal cancer, which delays diagnosis and treatment. In fact, this diagnostic method is simple and feasible. Through digital rectal examination, the size and degree of infiltration of the palpable mass can be determined, whether it is fixed, and whether there are implanted masses outside the intestinal wall or in the pelvic cavity.

Proctoscopy or sigmoidoscopy After the digital rectal examination, a rectal examination should be performed again to assist in diagnosis under direct vision, observe the shape of the mass, the upper and lower edges, and the distance from the anal edge, and take the mass tissue for pathological section examination to determine the nature of the mass and its degree of differentiation. For cancer located in the middle and upper rectum, which cannot be touched by fingers, sigmoidoscopy is a better method for diagnosing rectal cancer.

Barium enema and fiber colonoscopy are not very helpful in the diagnosis of rectal cancer, so they are not included in routine examinations and are only used to rule out multiple colorectal tumors.
