The way I read the article, they don't seem to be implying causation. The only realtion hinted at seems to be in the psychological state of women seeking breast implants and of women committing suicide. It's like old statistics on suicides at the Golden Gate bridge. The bridge doesn't cause the suicides, but a higher than mormal number of people travelling to the bridge from across the nation are suicidal compared with the normal population. They reach the bridge and find out it's the end of their quest and, having no further goal or hope for thier lives, no place further to travel to looking for personal meaning, decide to end their lives there as well.
The devil is ALWAYS in the details.
