Failure to control for confounding factors may explain previous reports of positive associations linking melanoma to sunscreen use. In addition, it may take decades to detect a protective association between melanoma and use of the newer formulations of sunscreens. " So this study appears to refute any link between sunscreen use and melanoma rates; i.e., sunscreen neither reduces nor increases the incidence of melanoma.

One flaw in your logic is that you cite Dennis et al, 2003 as proof that sunscreen doesn't prevent melanoma and then go on to argue that sunscreen <em>causes </em>melanoma when the same source (Dennis et al, 2003) concludes otherwise.  In fact, the objective of the review by Dennis et al was to determine if past research supported the claim that sunscreen contributes to melanoma and they concluded that it does not.

Mainly only when I know I'll be out somewhere long enough that I will guarantee to burn, severely,  if I don't use it. Otherwise I welcome the natural vitamin D. I always feel better doing so. As for sunglasses though... I have trouble seeing in sunlight, without them. And not just when driving, but anywhere, really. I even need them to drive safely, on bright, but cloudy days. If I loose them, I find myself squinting often. >.< This article made me feel better about the fact I rarely ever use sun screen.

Natural sunscreens can often be found at health-food stores. They're not cheap, but they're worth it. You can also use lightweight clothing.
