Research suggests that eating 150g of processed meat a day - the equivalent of around two sausages and three rashers of bacon - increases the risk of bowel cancer by 63 per cent.
However, just 34 per cent of British people are aware of the link, meaning that two thirds of people are unable to make an informed decision about how much processed meat they consume, according to Professor Martin Wiseman, medical and scientific adviser for the World Cancer Research Fund (WCRF).
The professor claimed that around a third of cancers could be prevented by eating healthily, leading an active lifestyle and maintaining a healthy weight.
He said: "For some people, having a fry-up with bacon and sausages might seem like a good way to start the day.
"[But] the more processed meat you eat, the greater your risk [of bowel cancer]."
Research has also shown that eating red meat, including beef, pork and lamb, can increase a person's risk of bowel cancer.
