Rectal cancer symptoms?

1、 Stool habit change: stool habit change is a typical symptom of rectal cancer. Due to the rectal mass and its secretions, it can produce intestinal irritation symptoms, resulting in frequent defecation, incomplete defecation, irritability and other symptoms, but the discharge is mostly mucus and pus. At this time, the shape of feces has also changed, and the stool is getting thinner and thinner. At first, these "pseudo diarrhea" phenomenon often occurs shortly after getting up in the morning, which is called "morning diarrhea". Later, the number of times gradually increased, even unable to sleep at night, changed the past defecation habits.

2、 Hematochezia: the early symptoms of rectal cancer are mainly painless hematochezia, and the blood is red or bright red, which is very similar to the symptoms of early internal hemorrhoids, so they are easily confused. In the late stage of rectal cancer, bloody stool is mostly dark red, mixed with mucinous bloody stool or pus bloody stool, sometimes accompanied by blood clots and necrotic tissue.

3、 Intestinal stricture and obstruction: intestinal stricture and obstruction belong to the symptoms of rectal cancer. In the late stage of rectal cancer, because the tumor infiltrates around the intestinal wall, the intestinal cavity is narrow, especially at the junction of rectum and sigmoid colon. Most of them are narrow type hard cancer, which is easy to cause obstruction.

matters needing attention

If there is a lack of fiber in the diet, the feces in the colon will become dry and hard. In addition, the speed of passage is slow, and the abdominal wall muscles become weak, so that the emptying time is prolonged. If the time is too long, the risk of rectal cancer will be relatively increased. Many studies have confirmed that the fiber in food can dilute the carcinogenic substances in oil, and also accelerate the speed of carcinogenic substances excreted through the digestive system.
