Janus Serum Bank Cohort in Norway
The Janus Serum Bank Cohort in Norway is a resource for research on the early detection and causes of cancer. Participants were initially recruited through four health surveys: Oslo Study 1 (1972-73), the Norwegian Counties Study (1974-88), the Age 40 Programme (1982-99), and the TROFINN Health Study (2001-03). Participants were also recruited from Red Cross blood donation lists beginning in 1973. Participants are from 18 of the 19 regions in Norway and were aged between 18 and 65 years at baseline, depending on where they were recruited. Follow-up periods vary depending on the health survey from which participants were recruited. As of 2024, the cohort includes over 318,000 individuals. As of December 2023, over 120,000 cancer cases were found in the Janus donors.
