As the polyps multiply and become malignant, symptoms are cultivated.

The most common symptoms include:

  • Blood in your stools. This may be mixed into your faeces or flecks on the surface, there may be a lot blood in the toilet pan or on the toilet paper. It’s a good idea to get into the habit of checking in the toilet before you flush.
  • Persistent changes in your bowel habit that last for longer than several weeks. This could be going to the toilet more often or having diarrhoea.
  • Weight loss without any obvious reason and/or losing your appetite.
  • Tiredness or breathlessness for no apparent reason. This may be caused by the small amount of blood loss from your bowel, which can result in anaemia. Anaemia is when there are too few red blood cells or not enough haemoglobin in your blood.
  • Pain, or a lump or swelling in your abdomen (tummy).

If any of these symptoms appear see your doctor immediately.
