A pilot study on respiratory and digestive tract cancer among woodworkers.

Cancer of the nose and paranasal sinuses is a known occupational hazard among workers in the furniture industry. An increased frequency of cancer at other sites has also been suggested to occur among different types of woodworkers in the United States, eg, cancer of the gastrointestinal tract and lung but also lymphatic and hematopoietic malignancies. This case-referent study is of a pilot character and was undertaken for the further elucidation of respiratory and digestive tract cancer among Swedish woodworkers. A four-fold excess of respiratory cancer, other than nasal cancer, was found, particularly in relation to furniture workers, whereas no definite excess of digestive tract cancer was indicated. Further studies seem worthwhile regarding cancer hazard in the woodworking industry.
