I heard something about underwire bras causing breast cancer. Well, unless they're using radioactive metal, I think it's a bunch of hogwash and decided to do some research.
Evidentally someone wrote a book and posed their own fantasy theory (to make their book sell) about this issue and now it has become a minor urban myth.
Please make sure your medical facts come from the medical experts, not gossip passed from one person to the next and definitely not from a non-expert trying to sell a book. Beware of conspiracy theories. There is no evil plot.
Never fear. Underwires do NOT cause cancer. Every single link shown below agrees with my hogwash opinion.
