What are the symptoms of colon cancer at different stages?

Colon cancer is a common digestive tract malignancy that occurs in the colon, ranking third among gastrointestinal tumors. The most common sites are the rectum and the junction of the rectum and the sigmoid colon, accounting for 65%. Most cases occur after the age of 40, with a male-female ratio of 2 to 3:1. The highest incidence rate is in the 40-50 age group. Let's take a look at the symptoms of colon cancer. The symptoms at different stages are also different. It is important to pay attention to prevention and treatment based on your own experience.

Most patients with colon cancer are middle-aged or older, with a median age of 45, and about 5% of patients are under 30 years old. The clinical manifestations of colon cancer vary depending on the size, location and pathological type of the lesion. Many patients with early colon cancer may have no clinical symptoms, but as the disease progresses and the lesion continues to grow, a series of common symptoms of colon cancer may occur, such as increased frequency of bowel movements, blood and mucus in the stool, abdominal pain, diarrhea or constipation, intestinal obstruction, general fatigue, weight loss and anemia.

The following are symptoms of colon cancer at different stages:

(I) Early symptoms: In the earliest stage, there may be abdominal distension, discomfort, and indigestion-like symptoms, 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.

(B) Symptoms of poisoning: Due to the blood loss caused by tumor ulceration and the absorption of toxins, patients may often experience anemia, low fever, fatigue, weight loss, edema, etc., among which anemia and weight loss are particularly prominent.

(III) 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 can reveal abdominal distension, intestinal type, local tenderness, and strong bowel sounds.

(IV) Abdominal mass: It is a tumor or a mass that has infiltrated and adhered to the omentum and surrounding tissues. It is hard and irregular in shape. Some of them may have a certain degree of mobility along the intestinal tract. In the late stage, the tumor infiltration is more severe and the mass may be fixed.

(V) Late stage manifestations: Signs of liver metastasis such as jaundice, ascites, edema, as well as cachexia, a mass in the anterior rectal fossa, and enlarged supraclavicular lymph nodes, which are manifestations of distant tumor spread and metastasis.
