How is right-sided intestinal cancer diagnosed?

Right colon cancer refers to colon cancer that occurs in the right side of the abdomen. The main symptoms are increased bowel movements, mucus and blood in the stool, and the tumor can grow and form strictures, followed by symptoms of intestinal obstruction such as abdominal distension and gas retention. About 75% of patients have abdominal discomfort or dull pain, which is intermittent at first and then becomes continuous, often located in the right lower abdomen, like a chronic appendicitis attack.

If the tumor is located in the hepatic flexure and the stool is dry and hard, colic may also occur, which should be distinguished from chronic cholecystitis. About 50% of patients have loss of appetite, fullness, belching, and nausea.

Abdominal mass: more than half of patients can find abdominal mass when they see a doctor. This mass may be the cancer itself, or it may be a mass formed by extraintestinal infiltration and adhesion. The former has a regular shape and clear outline; the latter has an irregular shape. The mass is generally hard in texture, and once secondary infection occurs, it is limited in movement and tender.
