title: Risk factors for squamous cell carcinoma of the skin in Saskatchewan, Canada.
abstract: Completed questionnaires regarding suspected risk factors for skin cancer were completed by 178 cases of SCC of the skin in Saskatchewan, Canada, and 284 age- sex- and location-matched controls. Significant risk factors identified using chi2 analyses were: farming, family history of skin cancer, light eye color, blond or red hair color, skin types I or II, obvious freckles in childhood, history of severe sunburn, and the use of the herbicide 2,4-Dichlorophenoxy acetic acid. The following relative risks were identified: (1) All cases of SCC of the skin and matched controls: agricultural occupation 1.49, history of severe sunburn 1.49. (2) All men with SCC of the skin and matched controls: history of severe sunburn 1.36 (3) All women with SCC of the skin and matched controls: agricultural occupation 1.83, and skin types I or II 1.48. No association was noted on our study between a history of psoriasis and development of SCC. Neither was an association between smoking and SCC found.
