Most patients with colon cancer are over 40 years old, and the incidence rate is high. If treatment is received in the early stages of the disease, the cure rate is very high, so understanding the early symptoms of the disease, early detection and early treatment will better protect our health. Generally, the early symptoms of colon cancer are as follows:

1. Symptoms of abdominal distension, discomfort, and indigestion may occur, followed by changes in bowel habits, such as increased bowel movements, diarrhea or constipation, and abdominal pain before defecation. Later, there may be mucus in the stool or mucus-purulent blood in the stool, which is the earliest symptom of colon cancer.

2. Manifestations of intestinal obstruction: Symptoms of incomplete or complete low-position intestinal obstruction, such as abdominal distension, abdominal pain (distension or colic), constipation or constipation. Physical examination shows abdominal distension, intestinal type, local tenderness, and strong bowel sounds.
