A world-first study led by University of Sydney has found that Australians aged 18-40 years who were regular users of sunscreen in childhood reduced their risk of developing melanoma by 40 percent, compared to those who rarely used sunscreen.
Melanoma is the most common cancer diagnosed in Australian men aged 25-49 years and second most common cancer in women aged 25-49 years, after breast cancer. Approximately two in three Australians will be diagnosed with melanoma or other types of skin cancer by the time they are 70 years old.
Published today in JAMA Dermatology, this is the first study to examine the association between sunscreen use with melanoma risk in young people under 40 years. The study analysed data collected from nearly 1700 people who participated in the Australian Melanoma Family Study.
“Our study shows that sunscreen use in childhood and adulthood was protective against melanoma in young people 18-40 years old, with their risk reduced by 35 to 40 percent for regular sunscreen users compared to people who rarely used it,” said lead researcher Associate Professor Anne Cust, who heads the Cancer Epidemiology and Prevention Research group at the University of Sydney’s School of Public Health and Melanoma
