I know that sun exposure is *essential* to produce vitamin D along with
cholesterol, and have read that patients with cancer all lack this vital
vitamin. Of course, exposure to sun means just that, not lying in it and
baking for hours! Dee

Actually, Nancy, I have read somewhere that sun exposure is not the real
cause of skin cancer (melanoma) but other contributing factors, and that
exposure to the sun (within reasonable limits) actually helps against
melanoma. But I dont have the source readily available. If sun exposure
alone were the cause of melanoma, one would expect the citizens of
equatorial or sun-drenched countries to be dropping like flies from this
cancer, but I have not heard such.
