Colitis is a difficult disease with a long course and easy recurrence. With the extension of the course of disease, the probability of colon cancer will increase. A long time ago, medical experts at home and abroad found that inflammation is closely related to cancer, and the risk of colon cancer in patients with colitis is as high as 40%. Medical experts also clearly pointed out that in order to reduce the occurrence of colon cancer, colitis should be completely cured in time. The main symptoms of colitis are diarrhea, purulent bloody stool, abdominal pain and acute diarrhea. Sometimes it will be accompanied by constipation and no defecation for several days. The course of the disease is long, the severity of the disease varies, and it is often accompanied by symptoms such as fatigue and emaciation, and it will often recur. However, the early symptoms of colitis are easily overlooked, and are often regarded as simple diarrhea and abdominal pain, which further expands colon inflammation and aggravates the condition, which is also the reason why taking medicine has no effect. Therefore, if these symptoms appear in the early stage, we must pay attention to them and find a regular hospital for examination and diagnosis. Among the clinically diagnosed patients with colon cancer, 60% suffer from colitis. They either treat diarrhea caused by colitis as general diarrhea and take some medicine casually, as long as they don't pull. Either it is diagnosed and not taken seriously, which makes the illness repeated and eventually leads to adverse consequences. Quantitative change leads to qualitative change. When colitis develops to a certain extent, colon cancer will occur. Only by completely curing colitis can colon cancer be avoided as much as possible. Therefore, patients with colitis must pay attention. Experts from Feng Runqinghua Hospital told patients over middle age that if they have the following manifestations, they should be vigilant and consider the possibility of colon cancer: ① The stool becomes thinner or there is blood and mucus; ② Changes in defecation habits (such as constipation, diarrhea or poor defecation), and recent persistent abdominal discomfort, dull pain or bloating; ③ The fecal occult blood test continued to be positive; ④ Abdominal palpable mass; ⑤ Unexplained anemia, fatigue or weight loss. If the patient has the above-mentioned suspicious phenomena, in addition to further medical history inquiry and physical examination, the following systematic examination should be carried out immediately to make a clear diagnosis.
