Recent research found that eating 50g of processed meat a day - the equivalent of a sausage or three rashers of bacon - increases the risk of bowel cancer by 20 per cent.
However, the World Cancer Research Fund (WCRF) is concerned that just 30 per cent of respondents to a survey were aware of the risk.
The association's medical and scientific adviser, Professor Martin Wiseman, commented: "We are more sure now than ever before that eating processed meat increases your risk of bowel cancer and this is why WCRF recommends that people avoid eating it.
"The evidence is that whether you are talking about bacon, ham or pastrami, the safest amount to eat is none at all."
Bowel cancer is the third most common form of the disease, with nearly 100 people being diagnosed every day in the UK.
