What are the symptoms of colon cancer

The early symptoms of colon cancer are not typical and are easily ignored by patients. In the early stage of the disease, there may be symptoms such as abdominal distension and indigestion. As the disease progresses, the patient's body will gradually become thinner and lose appetite. As the disease progresses, the patient's bowel habits will change and blood in the stool will appear. The following is an introduction to the symptoms of colon cancer:

(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.

The late-stage symptoms of colon cancer are very obvious, but the best time for treatment has been lost. For malignant tumors, timely detection of the disease is a very important aspect, but the early symptoms of colon cancer are generally not obvious. It is recommended to have regular physical examinations, especially for high-risk groups, so that the disease can be detected in time.
