2.1 Signs and symptoms
The following signs, symptoms and results should be investigated:
- positive iFOBT
- passage of blood with or without mucus in the faeces
- unexplained iron deficiency anaemia
- change in bowel habit (loose stools or constipation), especially a recent one that does not have another explanation such as an infection or opioids
- undiagnosed abdominal pain or tenderness
- unexplained rectal or abdominal mass
- unexplained weight loss (Cancer Council Australia Colorectal Guidelines Working Party 2019)
- lethargy.
The presence of multiple signs and symptoms, particularly in combination with other underlying risk factors, indicates an increased risk of colorectal cancer.
Presenting symptoms should be promptly and clinically triaged with a health professional.
