To measure the rate at which non-melanocytic skin cancers develop, we conducted a population-based, longitudinal study in Geraldton, Western Australia.
Subjects were residents of Geraldton, Western Australia, who were between 40 and 64 years of age and registered on the electoral roll in 1987.
In 1987 and again in 1992, dermatologists examined participants for skin cancers.
They examined all skin areas, apart from those covered by underwear or hair.
Subjects were asked about skin cancers that they had had treated between the 2 surveys.
When all skin cancers were counted, the incidence rates of basal cell carcinoma were 3,379 per 100,000 person-years in women and 7,067 per 100,000 in men ; those of squamous cell carcinoma were 501 per 100,000 in women and 775 per 100,000 in men.
Sixteen percent of men and 14% of women developed at least one basal cell carcinoma ; 2.8% of men and 2.2% of women had at least one squamous cell carcinoma.
Most incident skin cancers were diagnosed at the second examination.
More than half of the subjects who had a skin cancer at the first examination developed another.
Squamous cell carcinomas occurred almost exclusively on parts of the body that are usually exposed.
Basal cell carcinomas were common on the head, neck and trunk but not on the forearms and backs of hands.
A quarter of people with a skin cancer on an exposed site also had one on the trunk. (...)
