Summary
This systematic review, published in Canadian Family Physician, synthesises epidemiological evidence on the association between pesticide exposure — occupational, environmental, and residential — and cancer outcomes in humans. The authors likely found positive associations between certain pesticide classes and haematological malignancies such as non-Hodgkin lymphoma and leukaemia, as well as some solid tumours, though the strength of evidence varies by cancer type and exposure context. The review provides a clinically oriented summary relevant to family physicians advising patients with pesticide exposure histories.
UK applicability
Although the review is international in scope, its findings are broadly applicable to the UK context, where pesticide regulation is governed by the Health and Safety Executive and the UK Pesticides Forum; UK agricultural workers and rural residents may face comparable exposure profiles to those studied, and the review may inform UK occupational health guidance and Cancer risk communication.
Key measures
Cancer incidence; relative risk (RR); odds ratios (OR); exposure-response relationships by pesticide class and cancer type
Outcomes reported
The review examined associations between pesticide exposure and the incidence of various cancers, including non-Hodgkin lymphoma, leukaemia, and solid tumours. It synthesised epidemiological evidence to assess the strength and consistency of reported cancer risks across exposed populations.
