Cancer appears around us more and more frequently. What are the symptoms of intestinal cancer?
? Intestinal cancer includes colon cancer and rectal cancer, commonly referred to as colorectal cancer. Strictly speaking, colon cancer and rectal cancer are not exactly the same in symptoms, and the emphasis will be different, but the overall situation is similar, so they can also be discussed together. In most cases, early colorectal cancer has no obvious symptoms, but when the condition of colorectal cancer develops to a certain stage, there is a high probability that some symptoms may appear, which is the so-called omen. In fact, it is probably not a precursor, but a sign of later stage, because this cancer may have been advanced. So what are the symptoms of colon cancer?

? One is black stool or bloody stool.

? When there is a tumor in the intestine, the texture of the intestine is very fragile, and the feces will rub when passing through the cancer, which will cause the tumor surface to rupture and bleed, and some blood will oxidize and turn black in the intestine, then mix with the feces and finally discharge black stool; Repeated stimulation of intestinal mucosa by cancer cells can lead to intestinal bleeding, especially when the amount of bleeding is large, it is too late to be oxidized by the intestine, and it is directly discharged with feces, which makes the stool bloody.

? Second, the change of defecation habits.

? Diarrhea, constipation or alternating diarrhea and constipation may occur in the early stage. With the continuous growth of tumor, it leads to intestinal stenosis and progressive constipation. In addition to frequent defecation, patients with rectal cancer have a feeling of endless defecation, which first appears after getting up in the morning, and then gradually increases, several times a day or more than 10 times, and even defecation several times at night.

? Third, constipation and diarrhea appear alternately.

? If you have constipation and diarrhea for a while, you should pay special attention to it ~ If cancer occurs near the anus, the intestine will narrow and the feces will not pass easily, which will lead to constipation or stool thinning. At the same time, due to the narrowing of the intestine, in order to squeeze feces out of the intestine, the large intestine has to work harder to promote defecation, and the intestinal movement becomes active, which may also lead to diarrhea.

? Fourth, do not have too many abdominal masses.

? Some patients' abdominal pain is accompanied by a mass in the lower abdomen. Generally, we should pay more attention to this situation. Tumors are abnormally proliferating tissues, and intestinal tumors will be exposed to the lower abdomen when they grow up, which will attract your attention. Generally speaking, if it is really a tumor, it has reached this level, and it needs to be examined immediately to decide the treatment strategy.
