"...several large scale studies over the past few 
years had been "unable to tease out any clear 
relationship" between sunscreen use and melanoma 
incidence. But some studies showed sunscreens 
increased the incidence of melanoma..."

Have always been leery of sunscreens because never really
understood how they were supposed to "work", but used them
anyway.  Now, just use CS spray when going to the beach,
or know I'll be exposed to lots of sun, just as a matter
of course, but still left with a vagueness of its eficacy;
does it prevent burning/damage, or just speed up repair?
