Quebec City, September 19, 2006--A study conducted among 24,600 women by two Universit Laval Faculty of Medicine researchers and their colleagues from the Canadian Public Health Agency and Cancer Care Ontario concludes that having breast implants does not increase mortality risk. However, the study reveals that the suicide rate among women with breast implants is 73% higher than in the general population. These findings are published in a recent issue of the American Journal of Epidemiology.
Universit Laval's Jacques Brisson and Louis Latulippe and their colleagues collected information on 17,400 women from the province of Quebec and 7,200 from Ontario who had received breast implants for cosmetic purposes between 1974 and 1989. These women, who had undergone the surgery at an average age of 32, were the subject of regular follow-ups during a 15 year period. A total of 480 women with breast implants died during that period, and cross-referencing with the Canadian Vital Statistic Database was performed to determine the cause of death.
Researchers did not observe any increase in the mortality rate of women with breast implants. In fact, that rate was 26% lower than in the control group. Fewer deaths from cancer--notably breast cancer--and heart disease accounted for most of the discrepancy. The researchers insist that this lower mortality rate is not the result of the breast augmentation procedure itself, but rather of a double selection bias. "First, a woman must be in relatively good health to undergo breast implant surgery," points out Dr. Brisson. "Also, women who receive breast implants tend to be of higher-than-average socioeconomic status. Thus, women who undergo breast augmentation surgery are more likely to be in better health than the general population."
To put this explanation to the test, the research team analyzed a group of 16,000 women who had undergone plastic surgery procedures other than breast augmentation. As in the
