On the NBC Nightly News (May 25, 2010), NBC medical correspondent Nancy Snyderman, MD, discussed sunscreen use, disputing a charge made by an environmental group that sunscreens containing vitamin A may increase the chance of developing skin cancer.
After pointing out that the study to which the group referred was performed on mice, Dr. Snyderman stated, “I don’t see any evidence or proof that the use of sunscreens causes or promotes skin cancer” in humans.
She went on to advise viewers to wear sunscreen while outdoors and to look for products that protect against “UVA and UVB rays that cause skin cancer and … wrinkles.”
She added, and I agree, “Anything over an SPF of 50, you’re probably wasting your money.”
