How to determine rectal cancer

First: the clinical manifestations of rectal cancer, such as changes in defecation habits, bloody stools, purulent stools, tenesmus, constipation, diarrhea, etc., and the defecation gradually becomes thin. In the late stage, there are defecation obstruction, emaciation, and even cachexia. Digital rectal examination is a necessary examination step for the diagnosis of rectal cancer. About 80% of patients with rectal cancer can be found by natural digital rectal examination In the late stage, the intestinal cavity could be touched, and the dirty pus blood with feces could be seen in the fixed finger cuff.

Second: The determination of carcinoembryonic antigen (CEA) has been widely carried out. It is generally believed that it is valuable to evaluate the therapeutic effect and prognosis. Continuous determination of serum CEA can be used to observe the effect of surgery or chemotherapy. A significant decrease of CEA after surgery or chemotherapy indicates a good therapeutic effect. If the surgery is not complete or chemotherapy is ineffective, serum CEA is often maintained at a high level. If the CEA drops to normal after surgery and then rises again, it often indicates tumor recurrence.

Third: about 90% of rectal cancer, especially the lower rectal cancer, can be found only by digital rectal examination. However, there are still some doctors who do not do this routine examination for patients with suspected rectal cancer, so that the diagnosis and treatment are delayed. In fact, this diagnostic method is simple and feasible. Digital rectal examination can also determine the size and infiltration degree of palpable mass, whether it is fixed or not, and whether there is implant mass outside the intestinal wall or in the pelvic cavity.
