Three bowel movements a day and one bowel movement every three days, which one is the signal of bowel cancer? One article popular science

In recent years, the incidence of colorectal cancer in China has risen, and it has surpassed gastric cancer and has become the most common malignant tumor of the digestive tract in China, with more than 500,000 newly diagnosed colorectal cancer patients every year.

　　Moreover, because the early symptoms of colorectal cancer are atypical and difficult to attract the attention of patients, nearly 2/3 of colorectal cancer patients are diagnosed at an advanced stage.

　　Because of this, more and more people have raised their awareness of bowel cancer, and there are more and more popular science content about bowel cancer on the Internet.

　　These contents all mentioned "disordered bowel habits" without exception, which is affected by the stimulation of cancer and the changes in the secretion of the intestinal mucosa of the patient . , mixed with mucus in the stool, diarrhea and other symptoms.

　　However, after entering the middle and advanced stage of bowel cancer, because the cancer has grown to a certain extent, it may compress or block the bowel , resulting in the narrowing of the bowel lumen.

　　As a result, patients have symptoms similar to constipation, defecation becomes more and more difficult, and the shape of the stool may also change, such as the discharge of thin strips, flat strips, and one side of the stool with pits or bloodstains.

　　This jumble of content often confuses and even misleads readers. Some people think that as long as there are too many bowel movements a day or too few bowel movements, it is the manifestation of bowel cancer finding itself. So the question is, three bowel movements a day or one bowel movement every three days, which one is really bowel cancer?

　　In fact, from a clinical point of view, a healthy adult should have more than 3 bowel movements per week, and every bowel movement should be smooth and formed .

　　However, this data is not fixed, because the frequency of bowel movements is closely related to a variety of factors, including age, intestinal sensitivity, the type of food eaten, and the amount of food eaten .

　　Whether there is a disease in the intestines, we should not look at the frequency of individual defecation, but should pay attention to defecation habits. If your bowel movements are like this before, and the stools are formed and there is no abnormality, this is a healthy performance.

　　However, if the defecation habit is suddenly disrupted recently, such as one defecation a day before, and more than 3 defecations in a recent day, and the symptoms persist for at least two weeks without any relief , no matter how much you adjust your diet, this is possible. It's a sign of gut disease.

　　What needs to be emphasized here is that bowel cancer does cause disordered bowel habits. However, the appearance of disordered bowel habits does not necessarily equal bowel cancer.

　　Because there are many types of lesions that occur in the intestine, including intestinal infection, intestinal flora disorder, ulcerative colitis, Crohn's disease, irritable bowel syndrome , etc., they may change the patient's bowel habits , resulting in an abnormal increase or decrease in the number of bowel movements. Therefore, this symptom alone cannot be directly judged as a signal of intestinal cancer.

　　From a clinical point of view, bowel cancer not only leads to disordered bowel habits, but patients may also experience multiple abnormalities such as lower abdominal pain, weight loss, anemia, repeated fever, mixed bloody stools, and pus and bloody stools.

　　However, these symptoms are rare in the early stage, and basically appear in the middle and late stages of colorectal cancer. Therefore, if you want to know whether you have bowel cancer, it is not only necessary to look at your physical performance, but also to increase your vigilance for bowel cancer, to check in time when symptoms appear, and to conduct regular bowel cancer screenings.
