In plain language

In six surveys of 1,893 interventional cardiologists, about 4% self-reported a cancer diagnosis, most often breast, brain, and skin cancers among cases with known type. Without comparison groups, this cannot show that occupational radiation caused these cancers.

the full text

What it found

  • Pooled across six cross-sectional studies, 4.1% of interventional cardiologists reported cancer, with study prevalences ranging from 2% to 6%.

    Key figures: 77 of 1,893 ICs (4.1%); range 2% to 6%

  • Among 24 cases with a specified cancer type, breast and brain cancers were most common, followed by skin cancer, leukemia, and head and neck cancer.

    Key figures: breast 33.3%, brain 33.3%, skin 20.8%, leukemia 8.3%, head and neck 4.2% (n = 24)

  • More than 40% of interventional cardiologists in the included studies had over 15 years of occupational radiation exposure.

    Key figures: >40% with >15 years

  • Causality cannot be established because most studies lacked non-exposed comparator groups, relied on self-report, and did not address confounders.

  • The authors interpret reported left-sided brain tumors and breast cancers as consistent with exposure of unshielded head and arm-hole regions, and call for better shielding and health surveillance.

Limits to keep in mind

Small review of six self-reported cross-sectional surveys and four case reports, screened and extracted by a single reviewer, with no non-exposed comparator groups, no dose quantification, and no control for confounders such as age or smoking.
