But, just because you find blood in your stools, it doesn’t necessarily mean that you have bowel cancer.
A small amount of one-off blood isn’t usually caused by anything serious, said the NHS.
It may be caused by gastroenteritis, a bowel polyp, piles, or an anal fissure.
You should, however, dial 999 straight away if you find a lot of blood. For example, if the toilet water has turned completely red.
