In plain language
This review by medical physicists argues that evidence linking occupational radiation to brain tumors in interventionists is inconclusive. Reported operator head doses vary greatly, and the case series rely on self-report. The authors call for more rigorous dosimetry and epidemiology.

What it found
Reported operator doses from fluoroscopy-guided procedures vary widely, so typical operator exposure is unclear.
An updated case series reported 31 interventionists with brain tumors, mostly left-sided, but it relies on self-reported data.
Key figures: 22 of 26 cases left-sided
The authors note that other occupations also show increased glioma incidence and that left-sided tumors may be diagnosed earlier, suggesting factors other than radiation may be involved.
A hanging lead shield was associated with lower 3-month cumulative head dose in a cited study.
Key figures: 2.77 mSv without shield vs 0.22 to 1.16 mSv with shield
In a cited survey of cath lab professionals, some left cath lab work because of radiation concerns, while reported cancer diagnoses were low.
Key figures: 10.6% stopped working; 2.2% diagnosed with cancer; n=615
Limits to keep in mind
Narrative review by two medical physicists without systematic search methods; it summarizes heterogeneous dosimetry studies and weak epidemiologic evidence, and its interpretation (e.g., that career decisions reflected fear) is the authors' opinion.
