FYI
The great British breakfast
Bacon and sausages, the basis of a fry-up, are processed meats which are linked to an increased risk of developing bowel cancer.
And greasy additions of fried bread, fried egg and black pudding result in a hefty calorie count that can lead to obesity - and a raised risk of suffering a host of other types of cancer.
Lovers of the English-breakfast are 63% more likely to develop bowel cancer if they tuck into two sausages and three rashers of bacon daily, The World Cancer Research Fund (WCRF) warned.
The charity added that the evidence that processed meat is a cause of bowel cancer is so strong, people should avoid eating it.
There is also convincing scientific evidence that excess body fat is linked to six different types of cancer, including bowel cancer and breast cancer, the WCRF said.
Experts now believe that, after not smoking, maintaining a healthy weight is the most important thing people can do to prevent getting the disease.
Professor Martin Wiseman, medical and scientific adviser for WCRF, said: "For some people, having a fry-up with bacon and sausages might seem like a good way to start the day.
"But if you are doing this regularly then you are significantly increasing your risk of bowel cancer, which is one of the most common cancers in the UK.
"Only a third of people are aware of the link between processed meat and cancer, which means two thirds of people are not in a position to make an informed choice about how much of it they eat.
"This is not a question of all or nothing because the more processed meat you eat, the greater your risk.
"As well as the processed meat increasing the risk of bowel cancer, fry-ups also tend to be high in calories.
"We recommend people limit consumption of high calorie, or energy dense foods because eating them regularly makes you more likely to gain weight.
"This is important because there is convincing evidence excess body fat increases risk of six different types of cancer."
In terms of overall risk, the chances of developing bowel cancer are one in 18 for men and one in 20 for women in the UK.
