Description

The cohort consists of all individuals over 18 years with lymphoma identified from the regional cancer registry in southern Sweden during the years 1990 to 1998. In the first step the primary physician was contacted and after consent questionnaires were mailed to the patients. For each case, two controls matched for sex, age and place of residence and the same questions were also sent to them. The questionnaire addressed issues such as education, smoking, occupation and exposure to various substances. Participants were asked if they had had one of 25 specified occupations where you work with substances that may be hazardous, such as in the textile industry, the oil industry or in the rubber industry. The questionnaire also contained specific questions about the subjects had been exposed to any of 16 different subjects, eg nickel, asbestos, solvents, gasoline, other petroleum products, pesticides, radiation or radioactivity, and also the time of exposure. Further questions concerning what animals they had been exposed to both at home and outside the home.
