Sunscreens Can Slow the Development of Moles in Children:
A new study published in the Journal of the American Medical Association (JAMA) shows that using sunscreens appears to reduce the development of nevi (moles) in white children. About half of cancerous melanomas (a dangerous type of skin cancer) arise in moles. It is thought that by reducing the number of moles that develop, sunscreens can reduce the risk of developing melanoma later in life. In this study, 458 children were divided into a "test " group and "control" group.
Parents of children in the "test" group were asked to apply sunscreen (with a sun protection factor SPF of 30) to their child whenever they went outdoors for 30 minutes or longer. Parents of the "control" group were not given any advice on sunscreen use. The time spent outdoors was similar in both groups. After 3 years, the number of new moles was significantly lower in the "test" (sunscreen) group and appeared to have the greatest effect on children with freckles.
