How can rectal cancer be detected

Rectal cancer is a common recurrent disease in life. There are many treatments for rectal cancer, but there are still some issues that need to be paid attention to in the treatment of rectal cancer. People should pay attention to the common sense about rectal cancer in life. The prevention of rectal cancer is also very important. The following experts will give you a detailed introduction on how to detect rectal cancer.

Carcinoembryonic antigen (CEA) measurement has been widely carried out and is generally considered to be valuable for evaluating treatment effects and prognosis. Continuous measurement of serum CEA can be used to observe the effects of surgery or chemotherapy. A significant decrease in CEA after surgery or chemotherapy indicates a good treatment effect. If the surgery is not thorough or chemotherapy is ineffective, serum CEA often remains at a high level. If CEA drops to normal after surgery and then rises again, it often indicates tumor recurrence.
Ultrasound examination: For cases of rectal tumors found in ultrasound examination, further intrarectal ultrasound can be performed. This is a non-invasive examination developed in recent years. Its advantage is that it can determine the depth and range of rectal cancer invasion, and it is also valuable for determining whether there is lymph node metastasis. Liver ultrasound is particularly important to prevent missed diagnosis of rectal cancer liver metastasis.
Barium enema contrast imaging: Barium enema contrast imaging helps to understand and exclude multiple cancer foci in the large intestine. The imaging manifestations of rectal cancer are: nodular filling defects, mostly on the inner wall of the rectum, round and smooth or slightly lobed, local intestinal wall stiffness and concave. Cauliflower-shaped masses, large, uneven surface, obvious lobes, wide base, and stiff intestinal wall. Irregular annular stenosis, stiff wall, interrupted mucosa, and sharp boundaries. Irregular intracavitary niches, triangular, long strip, etc., shallow, with uneven width of surrounding ring embankments.
Rectal cancer always recurs, which makes patients with rectal cancer distressed. There are many symptoms of rectal cancer. People should pay attention to understanding them in life. If you suffer from rectal cancer, you should understand many small problems, such as diet, but you should also pay attention to treatment methods.
