Maternal health, in-utero, and perinatal exposures and risk of thyroid cancer in offspring: a Nordic population-based nested case-control study

This population based nested case-control study integrated registry data from Denmark, Norway, Sweden and Finland over 40 years to investigate the association of maternal, in-utero, and postnatal factors with thyroid cancer risk in offspring. Each patient with thyroid cancer (cases n=2437) was matched with 10 controls without thyroid cancer (n=24’362).
