Sun exposure is a major contributing factor for melanoma skin cancer, the fifth most common cancer in the UK, with more than 14,000 people diagnosed each year. A recent research suggests sunscreen alone should not be relied on to prevent malignant melanoma, a deadly form of skin cancer.
In the new study, scientists at the University of Manchester looked at the effects of UV light on the skin of mice at risk of melanoma. This allowed them to examine the effects of sunscreen in blocking the disease. "UV light targets the very genes protecting us from its own damaging effects, showing how dangerous this cancer-causing agent is," said lead researcher Prof Richard Marais. Very importantly, this study provides proof that sunscreen doesn't offer complete protection from the damaging effects of UV light. This work highlights the importance of combining sunscreen with other strategies to protect our skin, including wearing hats and loose fitting clothing, and seeking shade when the sun is at its strongest.
