Have you seen an ad on the Internet promoting a high-end bra that supposedly prevents or cures cancer? Beware! No such product exists. And those who let themselves be tempted run the risk of receiving nothing at all, or ending up with a poor-quality bra that neither prevents nor cures anything. A number of French women learned this the hard way when, for 30 euros, they bought a bra from Loovely or Nichon with a pink ribbon symbolizing the fight against breast cancer. These companies have since disappeared from the Web, but other fraudsters have taken over.
