Possible symptoms of right-sided colonic carcinoma include:

  • pallor, debility, breathlessness - due to iron deficiency anaemia caused by prolonged bleeding
  • loss of weight and anorexia
  • occult blood in faeces
  • persistent, dull ache in right iliac fossa, often postprandial and mistakenly attributed to gallbladder or gastroduodenal disease. This is a late symptom.

Less commonly:

  • intestinal colic and intestinal obstruction if the growth occludes the ileocaecal valve
  • acute appendicitis if the tumour blocks the mouth of the appendix, causing it to dilate
  • change in bowel habit, either constipation or diarrhoea but not both alternately
