It also explains that people who do go on to get diagnosed with bowel cancer usually have a combination of symptoms.
The combination could be one of the following:
- Persistent bowel habit changes such as going more often and blood in the stools
- a persistent change in bowel habits with abdominal pain
- blood in the stools without haemorrhoid symptoms, such as soreness, discomfort, pain, itching or a lump hanging down outside the back passage
- Abdominal pain and bloating after eating lead to less eating and weight loss
But in some cases, bowel cancer can also bring on fatigue. If the tumour bleeds, you can lose lots of blood – causing you to be low on red blood cells.
Red blood cells carry oxygen around your body, which is necessary for your body to create energy.
