What is the difference between intestinal polyps and intestinal cancer in symptoms?

Intestinal polyp is just a general term, which is a protruding and protruding lesion in the duodenal cavity. Any protruding lesion on the colonic mucosa can be called intestinal polyp, but there are many pathological types, which can be adenoma, inflammatory hyperplasia, local mucosal hypertrophy, cancer and so on.

It looks like a polyp to the naked eye, but it is actually a different disease with different prognosis and different treatment methods.

From my experience of colonoscopy, almost all polyps are asymptomatic, unless they grow in the rectum and sigmoid colon near the anal orifice, and there are large polyps, such as anal foreign body sensation and bloody stool, and only when they are huge enough to block the intestinal cavity will there be symptoms of obstruction.

Of course, some people will have nonspecific symptoms: especially large polyps can have occasional bloody stool, changes in defecation habits, abdominal pain, diarrhea, anal dilatation, changes in stool characteristics and other intestinal conditions, and the above symptoms lack specificity.

It is difficult to distinguish intestinal polyps from intestinal cancer only by symptoms, because the symptoms of all intestinal diseases are similar, such as common changes in defecation habits such as bloody stool, abdominal pain, constipation and diarrhea. If it is a special type of polyp (such as villous adenoma, etc.). ), frequent defecation, there will be mucus and incomplete defecation. If there are polyps in the rectum, there may also be discomfort caused by anal dilatation and heavy feeling after urgency. All the above are the same manifestations of intestinal polyps and early intestinal cancer. It is unrealistic to find early intestinal cancer through symptoms.

Of course, I would like to remind you here that if you have symptoms of bloody stool, especially mucus pus, you should attach great importance to it. No matter what causes hematochezia, unless hemorrhoids have been diagnosed before, it is best to see a doctor, and it is best to do colonoscopy to rule out intestinal cancer or colorectal polyps. Because the early stage of colorectal cancer is also a non-specific symptom, similar to the symptoms of polyps. If you don't care about the late development of intestinal cancer, it will be difficult to treat.

Advanced colorectal cancer can have unique symptoms, such as unexplained anemia, fatigue, loss of appetite, emaciation, indigestion, fever and other symptoms. These symptoms appear slowly, intestinal symptoms do not necessarily appear, and often do not attract the attention of patients, so it is found that some patients with intestinal cancer are in advanced stage; Symptoms such as intestinal obstruction, alternating constipation and diarrhea, bloody mucus and thin stool will only appear when the cancer in the middle and late stage of intestinal cancer breaks. Doctors don't want to attract everyone's attention when these symptoms appear. They should do colonoscopy early.

Conclusion: Adenomatous polyposis, inflammatory polyposis, porcine polyposis or familial adenomatous polyposis can all cause canceration. Therefore, it is suggested that people with normal intestines go to the hospital for further examination, and the diagnosis can be confirmed by double contrast examination of rectal digital examination, fibercolonoscopy or air barium enema. Do early detection, early diagnosis and early treatment.
