Risks of subsequent primary cancers at different sites according to personal history of non-melanoma skin cancer in men and women.

AR, age-standardized AR per 100,000 person-years.aRR adjusted for age (continuous variable).bMultivariate RR adjusted for age (continuous variable), BMI (31), physical activity (quintiles), smoking status (never, past 1–14 cigarettes per day, past 15+ cigarettes per day, current 1–14 cigarettes per day, current 15+ cigarettes per day), multi-vitamin use (yes or no), UV-index of residence at birth, age 15, and age 30 (≤5, 6, ≥7), physical examination in the last 2 y (yes or no), and menopause status and hormone replacement therapy use in women (pre-menopause, post-menopause non-user, post-menopause past user, and post-menopause current user). For breast cancer, we additionally included in the multivariate model duration of hormone replacement therapy use (pre-menopause, dubious menopause, post menopause age 40 kg), parity and age at first birth (nulliparous, parity 1–2 and age at first birth 5 and age at first birth 5 and 2531), family history of prostate cancer (yes or no), red meat consumption (continuous variable), fruit and vegetable consumption (continuous variable), and history of prostate-specific antigen testing (yes or no, lagged by one period to avoid counting diagnostic prostate-specific antigen tests as screening; collected from 1994 onwards). For melanoma, the multivariate model additionally included childhood reaction to sun (some redness or none, burn, painful burn or blisters), severe sunburns (none, 1–2, 3–5, 6–9, ≥10), moles on the left arm (none, 1–2, 3–5, 6–9, ≥10), hair color (black, dark brown, light brown, blonde, red), family history of melanoma (yes or no), sun exposures at different age intervals (continuous variable), UV index of residence at birth, age 15, and age 30 (≤5, 6, ≥7).cStatistically significant after correction for multiple comparisons, p
