The problem is that the author assumes that the increasing rate of cancer is due to ineffective sunscreen. But there are many other possible causes: For one, the use of sunscreen may give people a false sense of security, leading them to stay out in the sun longer than they would without sunscreen. Also possible is that advances in healthcare are allowing people to live much longer on average, which in turn has affected statistics as cancer becomes a larger problem to deal with among the elderly.

- euccastro 18y agoAnother possibility is that the rise in melanoma and the increase in sunscreen use are caused by the damage to the ozone layer and the corresponding social alarm, respectively. We have mostly forgotten about the ozone layer, but it was a hot topic not so long ago. OTOH, some 10 years ago, some sunscreen makes were forbidden (at least in Spain) because a component in them (I can't recall the name) had been proven to cause melanoma.
