Having breast implants doesn't directly affect your chance of committing suicide, but it does indicate that the woman behind the bogus boobs has lower self esteem, lower self-confidence, and higher rates of depression. After studying nearly 25,000 women, scientists found that the incidence of suicide among those with implants was 73% higher than the general population.
This increase is partially reflective of the demographic that has the money and desire to alter their physical appearance:
...the research team [also] analyzed a group of 16,000 women who had undergone plastic surgery procedures other than breast augmentation. As in the breast implant group, the mortality rate was lower (32%) and the suicide rate higher (55%) than in the general population.
What's the moral of the story? Who knows. But here's my advice: if you're a woman, make a real effort to appreciate who you are by not believing what the media tells you what you're supposed to be. And if you're a guy, keep telling your women the truth: you love them just the way they are!
