I confess, I haven’t seen the Today Show in years. But if I remember correctly spring goes something like this:
- Parade a bunch of $600 pairs of shoes out as the fresh new look of the season. Inspire women everywhere to wear knockoffs.
- Compliment the model, who will no doubt have dewy lips and a gorgeous tan.
- Bring out an expert waving a tube of sunblock and warning of the dangers of skin cancer.
- Break to commercial for sunless tanning lotion
Why do we want to be tan so badly? I think we are drawn to the healthy glow of sunkissed skin for the same reason men are drawn to women with hips: our instincts recognize indicators of good health even when it’s contrary to what the “experts” say. We agree with them in our minds, dutifully slather on SPF45, then run out and spend our money on dyes to make it tan again!
Let’s stop the madness. Sunlight prevents cancer.
No Really, I’m Serious
Insufficient exposure to ultraviolet radiation may be an important risk factor for cancer in Western Europe and North America, according to a new study published in the prominent Cancer journal that directly contradicts official advice about sunlight.
The research examined cancer mortality in the United States. Deaths from a range of cancers of the reproductive and digestive systems were approximately twice as high in New England as in the southwest, despite a diet that varies little between regions.
An examination of 506 regions found a close inverse correlation between cancer mortality and levels of ultraviolet B light. The likeliest mechanism for a protective effect of sunlight is vitamin D, which is synthesized by the body in the presence of ultraviolet B.
Cancer Journal, 94:1867-75 (emphasis mine)
Here’s what you need to know about this study: Sunlight reduced the instance of some of the deadliest cancers, such as breast, colon and prostate. In another study, clinical laboratory scientist Dennis Mangan concluded “This is like the Holy Grail of cancer medicine; vitamin D produced a drop in cancer rates greater than that for quitting smoking, or indeed any other countermeasure in existence.“
But What About Melanoma and Other Skin Cancers?
According to several studies low vitamin D status may actually contribute to the development of melanoma and other cancers.
[P]atients with malignant melanoma exhibit low levels of vitamin D3 in their blood [this study notes that the those who had the lowest levels developed metastatic disease faster], and . . . others have a problem with the receptor for vitamin D. (Hutchinson et al. 2000; Green et al. 1983) The incidence of melanoma of the skin on sites of the body intermittently exposed to sunlight is reduced among outdoor workers compared with indoor workers. (Elwood et al. 1985)
All of this points to a protective role for vitamin D against cancer in general, and melanoma in particular. But the final nail in the coffin of the “sunlight causes melanoma” hypothesis is this:
A comprehensive review of research studies from 1966 through 2003 failed to show any association between melanoma and sunscreen use! (Dennis et al. 2003)
Say what? Sunscreen doesn’t prevent skin cancer, that’s what.
But You Know What It Might Do? Cause Cancer!
It’s ironic, I know, but:
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, 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 takes a lick of it, it will kill them.
Is this really something you want on your skin?
Sunscreen Causes Cancer, Why Dance Around The Facts? (emphasis mine)
And here’s a fun fact from the London Sunday Times:
The main chemical used in sun lotions to filter out ultraviolet light may be TOXIC, particularly when exposed to sunshine.¹
Now, I’m not saying that sunscreen is directly responsible for the development of melanoma or any other particular cancers, but the slew of chemicals it contains have been shown to contribute to cancer. These chemicals don’t sit simply coat our skins, says clinical laboratory scientist Elizabeth Plourde. “Sunscreen is detected in the blood in five minutes and within hours it’s detected in the liver, kidneys, spleen, testicles and the brain. So we absorb it and it’s going into all our organs.”
And what do we have to show for it? In the last 40 years sunscreen use has increased by 30%, but at the same time skin cancer rates nearly quadrupled in parts of our population? “[If] sunscreen is meant to protect us, with its astounding popularity, one would think the skin cancer rates would at least stabilize, if not decrease,” right? ²
Convinced? Let’s Talk Solutions
Obviously sunlight is vital for health, but those skyrocketing skin cancer numbers are scary real, too. What’s causing them? Coming up in this series we’ll discuss theories about how oxidation works on a traditional diet vs. a Standard American Diet, why most “healthy” sunscreens contain ingredients that cause DNA deletions in mice, common sense sun safety, and how antioxidants prevent sunburn. Stay tuned!
Do you think sunscreen prevents cancer? Why or why not?
“Be wary of plastering yourself with sunscreen: not only may it be ineffective in filtering our UVA and UVB rays, it may be carcinogenic and also casue irreparable damage to aquatic environments.

In Sunscreens – Biohazard, inspired by a trip to sun soaked Hawaii and her reaction to bleached corals, she brings her scientific knowledge to bear on just how disruptive the chemicals in sunscreens really are.
