Sunscreen only a start
June 17, 2014
SUNSCREEN is not the only
measure that people should take to
avoid the effects of UV radiation.
Recent research, published in
Nature, investigated the molecular
basis of melanomagenesis and
demonstrated in mouse models
that sunscreen (UVA superior, UVB
sun protection factor (SPF) 50)
delayed the onset of UVR-driven
melanoma, but only provided
partial protection.
“UV light targets the very
genes protecting us from its own
damaging effects, showing how
dangerous this cancer-causing
agent is,” lead researcher Prof
Richard Marais told BBC News.
He said the work highlighted the
importance of combining sunscreen
with other strategies to protect
skin, including wearing hats and
loose fitting clothing, and seeking
shade.
