Ms. Gao, 56, is enjoying a full and comfortable retirement life. She tidies up her family every day and makes an appointment with several little sisters to have dinner every three or five times. No one can imagine that she has walked away from the edge of death. Things can be traced back to 16 years ago. When Ms. Gao was 40, she had some physical abnormalities. She found that her stomach was particularly uncomfortable for some time, her defecation was always unclean, and sometimes she had to go to the toilet two or three times a day. Subsequently, this abdominal discomfort became more and more serious, the number of defecation became more and more, and there was also bleeding. She felt that the situation was bad and rushed to the hospital. As a result, she was diagnosed with advanced colon cancer. Fortunately, after a series of treatment, Ms. Gao was successfully cured and returned to a normal life. The manifestations of colon cancer are diverse, but the following three points are easy to find in daily life. For the alarm signal of colon cancer, we should be alert to the following three points: Change of defecation habits by giving examples, normal people only need to defecate once a day, and the time is fixed. For example, when they get up to defecate every morning, their stomach will be relaxed after defecation, and they don't have to care about it this day. This is a very standard and most common situation. However, if for a period of time, I don't know why, the number of defecation per day increases to two or three times, and the regularity of defecation has disappeared. For example, the habit of getting up early to defecate has disappeared, and the number of defecation has to be increased at noon and at night; In addition, the original sense of ease after defecation also disappeared. This is the law of defecation times and the change of defecation feeling, which is called the change of defecation habit. Normal people defecate once a day. If the number of defecation increases suddenly and the time is irregular, it indicates that the defecation habit has changed. The change of stool character refers more to the shape. The most standard defecation is called banana like defecation, which looks like banana. If the stool is dry, hard and shapeless for unknown reasons, or it appears as a paste like, thinner, grooved and indented, it indicates that there may be a mass in the intestine, resulting in the change of stool shape. The reason behind it is actually well understood. If there is a lump in the intestine that stimulates the intestine, patients will often want to go to the toilet. If the mass is blocked in the intestinal cavity, the stool is not easy to come down, and the water is absorbed over a long time, resulting in dry and hard stool. The stool becomes thinner, has grooves and pressure marks, which is also due to the mass blocking in the intestinal tract, resulting in the space occupying effect and squeezing the stool. As we all know, as long as there is bleeding, we must be vigilant. If there is a tumor in the colon, the texture is very fragile. When the tumor rubs with the intestinal wall and feces, it is easy to break. Once broken, the blood flows into the intestinal cavity. There are some colon tumors, polyps and colorectal cancer, which have the function of secreting mucus; The mass inflames and breaks in the intestine and stimulates the intestinal wall. The normal colonic mucosa of the human body will secrete mucus and play a lubricating role. However, in morbid cases, excessive stimulation will lead to hypersecretion, so there is more mucus. The occurrence of mucus or bloody stool indicates that there may be a mass in the intestine to stimulate the intestinal wall. (outlook new era)
