Skin cancer in a Queensland population.

In the present study we have estimated the current prevalence of actinic skin disease in young and middle-aged adults in Queensland, Australia by surveying a representative community. It was found that 4.6% of persons aged 20 to 69 years had skin cancer, mostly basal cell carcinoma, and 40% had solar keratoses. The age distribution and site distribution of actinic lesions in this population were not as classically described; persons below age 40 years exhibited substantial sun-related skin damage, and a large proportion of actinic lesions occurred on sites other than the head, backs, of hands, or forearms. Allowing for age and sex, the strongest risk factors for skin cancer and solar keratoses were fair skin, as assessed by a dermatologist, and clinical signs of solar damage such as solar lentigines, facial telangiectasia, and actinic elastosis of the neck. Associations with self-reported tendencies toward sunburn, frequent painful sunburns, occupational sun exposure, and a previous history of skin cancer were confirmed.
