Bowel cancer symptoms
Cancer Institute NSW
Published 28 June 2018
In addition to participating in bowel cancer screening, there are symptoms that you can look out for to improve your chance of early detection.
- Bleeding—Blood in the stools (faeces/poo) or bleeding from the rectum.
- Changes in bowel habit—A persistent change in usual bowel habit such as more or less frequent bowel movements (or the feeling of having to go more frequently), or looser (more diarrhoea-like) stools.
- Pain—Abdominal pain, discomfort or bloating. You may also feel a lump or mass in your tummy or pain in the rectum.
If you have one or more of the above symptoms it is important to see your doctor, even if you have taken the bowel cancer screening test.
Some bowel cancer symptoms are even more subtle or non-specific, and can include:
- feeling of needing to strain (as if you need to pass a bowel movement) or feeling that the bowel has not emptied completely after passing a bowel movement
- unexplained weight loss
- unexplained tiredness
- feeling light headed (dizziness)
- weakness
- breathlessness
- unexplained anaemia (low red blood cells).
