Beach Walk 673 – Sunlight and Skin Cancer

You know I like to present the other side of the coin frequently, and today this regards the blind allegiance to sunscreen and fear of the sun that has been commercially developed over the past decade. There’s ample research that sunlight also prevents skin cancer, and the increase in skin cancer actually correlates nicely with the increase in sunscreen! You can hear my watch my first treatise on this here, just keep in mind I shot and edited that myself, and it’s a little long. The info is still good though! I hope you hop over – there are a lot of good links in that post!

For the locals; I shot this at the boat ramp. Hard to understand how we have lost so much sandy beach front in only 2.5 years.

Beach Walk 67 – Sunscreen & Skin Cancer: Hmmm

I am learning that something I thought was certain is not only far from it, but may prove to be the opposite of what I thought! Jeez, I don’t like this.

Do you find it strange that skin cancer rates have increased significantly since the introduction of sunscreens? There was a class action lawsuit filed recently against several sunscreen manufacturers. I used to “know” that sunscreen prevents skin cancer and have used it by the boat load, being an active person who loves the outdoors and a person with many relatives who have had cancer.

But apparently I have been living with a false sense of security, perpetuated I believe by the chemical sunscreen industry. In a nutshell, sunscreen can prevent sunburn. But it cannot block out much of the UVA that causes DNA damage and is the likely culprit for the more serious kind of skin cancer. Yet used enough, it can block the body’s production of Vitamin D, which is helpful in preventing cancer! Chemical sunscreens also contain petroleum-based and other chemicals that may be cancer agents. I found one study that also showed these sunscreens increase the skin absorption of herbicides. Not a pretty picture for farm workers or serious gardeners.

I am in a bit of shock as I thought this was a “done deal.” Using a physical sun block, also called inorganic, appears to be aok as it reflects the sun off the skin, as compared to chemical or organic sunscreen that absorbs the sun rays, producing this little chemical soup on/in your skin. Zinc oxide is my new plan.

If you used sunscreen and got skin cancer, you can join the lawsuit here.
