To tell the truth, what abnormal defecation may be a signal of colorectal cancer?

1, black stool: If you find abnormal stool color in the process of defecation in your life, you need to be alert, which is probably a signal caused by colorectal cancer. Because in the development of colorectal cancer, the intestinal tract is seriously damaged, which may lead to obvious bleeding. After blood is oxidized, the discharged feces will appear black, which is related to the increase of iron content in feces. Normal people's feces should be yellowish brown. When you notice black feces, you need to beware of colorectal cancer and seek medical attention in time.

2, abdominal pain during defecation: In the process of defecation, if you feel obvious abdominal pain, you need to be vigilant. Because the canceration of the intestine usually leads to intestinal obstruction, or the intestine is oppressed by cancerous tissue, there will be obvious pain at this time. Especially in the process of defecation, when feces pass through the intestine, the symptoms of oppression will be more obvious, so there will be abdominal pain during defecation.

3, diarrhea and constipation appear alternately: in the process of defecation, if you find that your feces are always abnormal, then you need to be alert to colorectal cancer. People who often have diarrhea and constipation alternately may suffer from colorectal cancer. Intestinal function is impaired, and diarrhea may occur. If intestinal stricture or obstruction has been found, it is difficult to discharge feces, and constipation usually occurs. If constipation and diarrhea often occur alternately in a short period of time, you need to be highly alert to colorectal cancer.

4. Mucus: During defecation, there is usually no mucus stool. Some people find a lot of mucus in their feces when they defecate. After defecation, you need to wipe the anus clean with a lot of paper towels. This situation may also be related to the short colon, because after colorectal cancer changes, the intestinal function is damaged, so the feces will easily become sticky and may have mucus. In view of this performance, it is necessary to carry out intestinal health examination in time.

5, bloody stool: bloody stool is similar to black stool, and it is also a symptom of bleeding from colorectal cancer. The tumor in the upper part of the large intestine bleeds and turns black after oxidation. But the bleeding in the lower segment of the large intestine is usually eliminated without oxidation, and then there will be blood. Therefore, when there is blood in the stool, you can't simply think that hemorrhoids have been committed. You should check it in time to rule out colorectal cancer.
