Causes & Risks
Causes & Risks
Although the exact cause of bowel cancer is unknown, there are
certain factors that may increase your risk.
Gender and age
Bowel cancer affects both men and women. In the UK, around 95%
of cases occur in people over the age of 50
Family history
People with a first degree relative (such as mother,
father, brother, sister, child) under 45 or with two or more first
degree relatives with bowel cancer may be considered for further
testing
Diet and lifestyle
An inactive lifestyle and a poor diet that is low in fresh fruit
and vegetables may increase the risk of bowel cancer. A high intake
of red and processed meat, smoking and excess alcohol may increase
the risk
Other conditions
People with diabetes, a history of Crohn's disease in the large
bowel, or ulcerative colitis, or who have had previous polyps
removed, may also be at an increased risk
