There is also sorne evidence of an association between nasal carcinomas other than adenocarcinoma and work as a carpenter. ln a case-control study based on an analysis of occupational data in the hospital records of 121 men seen for nasal cancer in British Columbia, Canada, between 1939 and 1977, a relative risk of2.5 (adjusted for smoking and ethnie origin) was associated with exposure to wood.
