Sunscreen Warning Labels On UV Exposure Urged At NIH Workshop

Use of warning labels on sunscreens to inform consumers UV damage may occur despite use was strongly recommended by Michael Holick, MD/PhD, Boston University School of Medicine, at the National Institutes of Health research workshop on UV risks and benefits in Bethesda, Md. Sept. 17.

AAD counters Berwick analysis that skin cancer may occur regardless of sunscreen use.

AAD COUNTERS CLAIM THAT SKIN CANCER LIKELY REGARDLESS OF SUNSCREEN USE in a March 12 letter from former President Roger Ceilley, MD, to epidemiologist Marianne Berwick, PhD, Memorial Sloan-Kettering Cancer Center. Ceilley's letter responds to a presentation given by Berwick before the American Association for the Advancement of Science in which she claimed study data suggest some individuals are "likely to develop skin cancer regardless of the amount of sunlight exposure or protection from sunscreen." In Ceilley's letter, the American Academy of Dermatology maintains "there are no data to support that statement."

Sunscreen for skin cancer prevention claims questioned by researcher.

SUNSCREEN FOR SKIN CANCER PREVENTION CLAIMS QUESTIONED by a Memorial Sloan-Kettering Cancer Center researcher in a presentation to the American Association for the Advancement of Science annual meeting in Philadelphia Feb. 17. Based on an analysis of 10 studies of sunscreen use and development of the skin cancer melanoma, epidemiologist Marianne Berwick, PhD, said: "Until the mechanisms for initiation and promotion for skin cancer are clearly elucidated, it would be well to take great care in the claims for either prevention of skin cancer by sunscreens or promotion of skin cancer by sunscreens".
