Products, are they to blame?

sooo new studies show that vitamin D reduce your risk of cancer (skin, colon, breat) by 77%.skin cancer as well? how does that work later? we've been told that you have need of sunscreen in lay down to fend off skin cancer, but in a minute its proven we need the sun's rays to protect ourself from this cancer. I infer its all the synthetic products,combining next to the UV rays/pollution that actually cause skin cancer.Is this possible? who knows more in the region of this?Products, are they to blame?

At one point or another everything have been said to grounds cancer. It changes month by month, so who know.
