Summer sun safety
Research reveals significant link to melanoma
Fifty years of medical studies show that sun exposure is a primary component in the development of melanoma, the most serious and deadly type of skin cancer, report leading dermatologists in the April 2006 issue of Dermatology Surgery.
“Though genetics may play a role in the development of some melanomas, theres overwhelming evidence that shows sun exposure adversely affects patients both with and without genetic predisposition to melanoma,” said Elisabeth K. Shim, M.D., an Associate Clinical Professor of Dermatology at Keck USC Medical School of Medicine in Los Angeles, CA.
Its not clear what pattern of sun exposure causes melanoma or whether its short, intense intermittent or cumulative. Further more, its not clear if ultraviolet B (UVB), ultraviolet A (UVA) rays, or both are responsible for causing melanoma. “Regardless, the sun acts as an initiating and promoting agent in causing melanoma, and causes immunosuppression,” noted Dr. Shim.
With summer quickly approaching, its necessary to protect yourself by using sunscreen and sun protective measures to prevent melanoma, and other skin cancers, despite current controversy.
