Britain's biggest-ever look at breast augmentation surgery found that members of the British Association of Aesthetic Plastic Surgeons (BAAPS) carried out 6 497 breast enlargements in 2007 compared to 2 361 in 2002.
BAAPS secretary Rajiv Grover, a plastic surgeon in London, collated the information and studied the data, which was presented at the association's annual conference in Chester, northwest England.
"The reason why we have this enormous increase is down to a number of factors, including improvements in surgery, shorter stays in hospital and shorter scar periods," he said.
"People used to think that breast augmentation was open only to celebrities and film stars - whereas they are now aware that the procedure is open to all members of the public, should it be right for them."
The study of 26 852 wider BAAPS operations found an average rate of infection of 0.53%, while 1.2% in haematoma (bleeding).
