Up to 40 percent of women with breast implants want them out, according to a new study conducted by the British Columbia Centre of Excellence for Women’s Health. The reason most commonly cited: Health complications. Said the lead researcher: “This wasn’t a study to lead us to say that because women got breast implants, they got sick, or they had problems. But, there is obviously something going on that is affecting their health, or women whose health does not support having a breast implant are still being given them.”
