The study, from Weill Cornell Medicine and NewYork-Presbyterian Hospital, and published in the journal Science, found that specially bred mice developed larger tumours when they consumed the equivalent of one can of soft drink per day.
Scientists studied mice that were genetically engineered to develop colon tumours. They gave one group a dose of high-fructose corn syrup (HCFS),Â a common sweetener in the US,Â that was equivalent to one can of fizzy drink every day for eight weeks. The other group did not receive any added sugars.
When researchers compared the size of the tumours in both groups, they found the ones that were fed HFCS had larger tumours than the ones who did not.
â€œWe were not able to show that giving high-fructose syrup causes new tumours, because these mice develop tumours even on normal diets free of added sugar,â€ explained the studyâ€™s lead author Dr Marcus Goncalves.
â€œBut when you give them this additional sugar, the tumours grow much bigger.â€

Colon cancer typically starts as a polyp, or a small group of cells, that carries on growing until it becomes a tumour.
â€œPolyps love to eat fructose and glucose and they use it to grow. Theyâ€™re just like humans,â€ Dr Lewis Cantley, one of the lead authors from Weill Cornell Medicine saidÂ in a statement.
â€œWhile our work was conducted in mice, our findings build on mounting evidence that sugar fuels cancer growth.â€
Though more research is needed to demonstrate whether HFCS promotes colon tumour growth in humans, study authors believe the findings could be used to advise about future cancer treatment or prevention.
They say their results suggest that people with colon cancer or those at high risk of developing it should avoid sugary drinks.
Though the effect of table sugars, wasnâ€™t measured in the experiment, researchers believe they are likely to produce a similar effect.
The study results follow a further piece of research published earlier this week,Â published in the journal Circulation, which found that drinking just one fizzy drink a day significantly increases your risk of heart disease.
The research found that those who consume two or more sugar sweetened beverages (SSBs) a day have a 31% higher risk of early death from heart disease.
Research conducted by scientists from Tehran University of Medical Sciences in Iran, discovered a link between drinking boiling hot water and the development of cancer of the oesophagus.
