First, the change of defecation habits may be the earliest symptom of colorectal cancer. Most patients show increased frequency of defecation, irregular or thin stool, bloody stool and mucus. Sometimes it is manifested as intractable constipation, and the shape of stool becomes thinner, which is caused by the intestinal cavity stenosis caused by the distal carcinoma of the large intestine.

Second: often with bloody stool as the prominent performance, or dysentery like purulent bloody stool, diarrhea, because of lower colon or rectal cancer caused by erosion and necrosis. Small intestinal tumors are often diagnosed as abdominal pain, black stool or bloody stool. Mixed blood and feces show jam like stool. Intestinal cancer often has erosion, necrosis and secondary infection, which increase the corresponding intestinal peristalsis, intestinal spasm, and cause abdominal pain of different nature and degree.

The obstruction caused by intestinal stenosis caused by the spread and infiltration of intestinal cancer around the intestinal wall is often chronic incomplete mechanical intestinal obstruction. Abdominal distension and discomfort first appear, and then paroxysmal abdominal pain, excessive bowel sounds, constipation or fecal degeneration appear.
