Solar ultraviolet radiation exposure, and incidence of childhood (0-19 years) malignant and non-malignant brain tumour in a US population-based dataset, 2000-2021.

Equally, there is a highly significant decreasing trend of both types of tumour with UVR-cumulative radiant exposure ( p < 0.0001).

Set against these findings, a case–control study of early childhood (ages 0–5) tumours nested within the California cancer registry, and using, like the present study, AVGLO ground-based assessments of UVR exposure, suggested a borderline significant increase in intracranial/intraspinal embryonal tumours among those with the highest level (among four quartiles) of UVR exposure [ 12 ] (birth-year-adjusted OR for 4th quartile = 1.26, 95%CI 1.00–1.61; birth-year-, maternal age-, race- and child’s birth-year-adjusted OR for 4th quartile = 1.29, 95%CI = 1.01–1.65).
