Bowel cancer is a general term for cancer that begins in the large bowel. Depending on where the cancer starts, bowel cancer is sometimes called colon or rectal cancer.
Cancer can sometimes start in the small bowel (small intestine), but small bowel cancer is much rarer than large bowel cancer.
Bowel cancer is one of the most common types of cancer diagnosed in the UK, with around 40,000 new cases diagnosed every year.
About 1 in every 20 people in the UK will develop bowel cancer in their lifetime.
The three main symptoms of bowel cancer are blood in the stools (faeces), changes in bowel habit – such as more frequent, looser stools – and

However, these symptoms are very common and most people with them do not have bowel cancer. For example, blood in the stools is more often caused by haemorrhoids(piles), and a change in bowel habit or abdominal pain is usually the result of something you have eaten.
As almost 9 out of 10 people with bowel cancer are over the age of 60, these symptoms are more important as people get older. They are also more significant when they persist despite simple treatments.
Most people who are eventually diagnosed with bowel cancer have one of the following combination of symptoms:
The symptoms of bowel cancer can be subtle and don’t necessarily make you feel ill.
Symptoms of Bowel Cancer
Your doctor will probably carry out a simple examination of your tummy and bottom to make sure you have no lumps.
They may also arrange for a simple blood test to check for iron deficiency anaemia – this can indicate whether there is any bleeding from your bowel that you haven’t been aware of.
In some cases, your doctor may decide it is best for you to have a simple test in hospital to make sure there is no serious cause for your symptoms.
Make sure you return to your doctor if your symptoms persist or keep coming back after stopping treatment, regardless of their severity or your age.

It’s not known exactly what causes bowel cancer, but there are a number of things that can increase your risk. These include:
Some people have an increased risk of bowel cancer because they have another condition that affects their bowel, such as severe ulcerative colitis or Crohn’s disease, over a long period of time. Read More About: Causes of Bowel Cancer — Preventing Bowel Cancer
To detect cases of bowel cancer sooner, the NHS offers two types of bowel cancer screening to adults registered with a GP in England:
Screening plays an important part in the fight against bowel cancer as it can help detect bowel cancer before it causes obvious symptoms, which increases the chances of people surviving the condition. Read More About: Screening for Bowel Cancer
Bowel cancer can be treated using a combination of different treatments, depending on where the cancer is in your bowel and how far it has spread.
The main treatments are:
As with most types of cancer, the chances of a complete cure depends on how far it has advanced by the time it is diagnosed. If the cancer is confined to the bowel, surgery will usually be able to completely remove it.
Overall, 7 to 8 in every 10 people with bowel cancer will live at least one year after diagnosis. More than half of those diagnosed will live at least another 10 years. Every year, around 16,000 people die as a result of bowel cancer. Read More About: How Bowel Cancer is Treated and Living with Bowel Cancer.
