Sunscreen Causes Cancer

One might find it a little strange that an organization as stringent as it would like people to believe such as the FDA would not publish firmly established safety guidelines for sunscreens and sunblock products for nearly thirty years.

It might seem even stranger that the FDA hasn't published regulations of any kind of sunscreens, considering that many of the ingredients used in them are dangerous chemicals, known to be environmental hazards, cancer-causing (carcinogenic), and disruptive to the endocrine system of the body, particularly sex hormones.
These chemicals are often absorbed directly through the skin.

Recent studies have shown that wide use of sunscreens does not result in a decrease in cancer--sometimes, sometimes often, showing quite the opposite tendency.

This could be due to the fact that sunscreens block the ultraviolet rays from the sun that, in small quantities, generate the extremely powerful anticarcinogenic vitamin D in human skin. Recent studies show that adequete values of vitamin D in the human body could perhaps reduce the occurence of most cancers by 80%.
That's pretty epic.

A large-scale analysis by a private organization, the Environmental Working Group (EWG) found that about 84% of the sunscreens they tested with an SPF (sun protection factor, or solar protection factor) over 15 in rating contained ingredients that raised significant health concerns for applicants of the sunscreen.

It is a little-known fact that many of the most popular sunscreen chemicals break down into useless (at best) or carcinogenic and environmentally hazardous (at worst).

Some chemicals to watch out for, since most of them are carcinogenic, break down into things that are, or generally just damage the body in other ways: just about anything with "benzo" in the name, PAB and PABA and their esters, cinoxate, ethylhexyl, p-methoxycinnamate, salicylates such as ethylhexyl salicyclate, homosalate, and octyl salicyclate, digalloyl trioleate (doesn't that just sound nasty?), menthyl anthranilate, and propylene glycol.

Wait, isn't glycol antifreeze?
Yes.
Yes, it is.
What's funny about antifreeze (Pardon me, "humectant".) found in sunscreen is that all the safety hazard sheets will tell you, regarding propylene glycol, to avoid contact with skin--and that it can cause liver abnormalities.
And that if it is spilled, and an animal tacks a lick of it, it will kill them.
Is this really something you want on your skin?

Always question.
