1. Symptom 1: defecation habit. Symptoms often appear in the early stage, such as increased defecation times, diarrhea, constipation, blood, pus or mucus D in feces, especially in left colon cancer. The closer the lesion is to the rectum, the more obvious the above manifestations are.
2. Symptom 2: Abdominal pain. It is also one of the early symptoms, and the pain is different in nature, which can be dull pain, colic and dull pain. Generally speaking, the specific location of its dull pain is uncertain, and sometimes abdominal distension and abdominal pain will occur, and abdominal pain will be aggravated or paroxysmal colic will occur when intestinal obstruction occurs.
3. Symptom 3: Abdominal mass. Most of them are caused by the tumor itself, but also by the periintestinal inflammatory reaction caused by cancer invading the whole intestinal wall and the adhesion of adjacent organs or intestinal curvature, and sometimes by the accumulation of feces in the proximal intestinal cavity. The masses are mostly hard, nodular, fixed or unfixed, and often adhere to the surrounding tissues with infection. The masses are fixed and have obvious tenderness.
