The risk of childhood cancer has been inconsistently linked with parental exposure to occupational agents, partly because of poor assessment of past exposure.
This project investigated data from the UK Childhood Cancer Study (UKCCS), a nationwide population based case control study, extending previous analyses of parental occupational exposures assessed via a job exposure matrix of job and industry titles. Eight specific work related exposures have been examined as possible risk factors for childhood leukaemia and lymphoma for three exposure time windows (preconception, pregnancy, postnatal).
