What are the main obvious manifestations of colon cancer symptoms

If we want to detect the presence of colon cancer around us as early as possible, we must first have a certain understanding of the symptoms of colon cancer. What are the most common symptoms of colon cancer ? Let the experts introduce the symptoms of colon cancer in detail.

(1) Abdominal pain and digestive tract irritation symptoms: Most patients with colon cancer have varying degrees of abdominal pain and discomfort, such as dull abdominal pain, right-sided abdominal fullness, nausea, vomiting, and loss of appetite. Symptoms often worsen after eating, sometimes accompanied by intermittent diarrhea or constipation, and are easily confused with chronic appendicitis, ileocecal tuberculosis, ileocecal segmental enteritis, or lymphomas that are common in the right lower abdomen. Hepatic flexure cancer of the colon can present as paroxysmal colic in the right upper abdomen, similar to chronic cholecystitis. It is generally believed that pain from right-sided colon cancer often reflects to the upper part of the navel; pain from left-sided colon cancer often reflects to the lower part of the navel. If the tumor penetrates the intestinal wall and causes local inflammatory adhesions, or forms a local abscess after chronic perforation, the pain site is where the tumor is located.

(2) Abdominal masses: The symptoms of colon cancer are generally irregular in shape, hard in texture, and nodular on the surface. In the early stages of transverse colon and sigmoid colon cancer, there is a certain degree of mobility and mild tenderness. If ascending or descending colon cancer has penetrated the intestinal wall and adhered to the surrounding organs, chronically perforated to form an abscess, or pierced through adjacent organs to form an internal fistula, the mass is usually fixed, with unclear edges and obvious tenderness.

(3) Changes in bowel habits and stool characteristics: The symptoms of colon cancer are the result of ulcers and secondary infections caused by tumor necrosis. Bowel habits change due to toxins stimulating the colon, with an increase or decrease in bowel movement frequency, and sometimes diarrhea and constipation alternating. There may be abdominal cramps before defecation, which are relieved after defecation. If the tumor is located lower or in the rectum, there may be symptoms of rectal irritation such as anal pain, difficulty in defecation, or tenesmus. The stool is often unformed and mixed with mucus, pus, and blood. Sometimes it contains a large amount of blood and is often misdiagnosed as dysentery, enteritis, hemorrhoidal bleeding, etc.
