Sigh. More likely, it's related to the genetics of the parents who turned to in vitro fertilization because of infertility, the study's Swedish authors and other experts say.
Yeah, I know...it's not a drastic difference in cancer risk, nor will a lot of people care if they really want that BAYBEEEE, but godDAMN. IF YOU CANNOT CONCEIVE NATURALLY, NATURE IS TRYING TO TELL YOU SOMETHING. YOUR GENES ARE NOT FIT TO PASS ON IF YOU CANNOT CONCEIVE. THAT IS HOW NATURE WEEDS THINGS OUT. PERIOD, END OF STORY. Just because the technology exists doesn't mean you should take advantage of it, and if it takes a child's potential cancer risk to curb your selfishness, then so be it. Self-serving assholes.
