Electromagnetic field exposure and male breast cancer risk: a meta-analysis of 18 studies.

Published in: Asian Pac J Cancer Prev 2013; 14 (1): 523-528

Aim of study (acc. to author)

A meta-analysis was conducted to evaluate the potential risk of male breast cancer associated with electromagnetic field exposure from all available sources.

Further details

Following 7 case control studies and 11 cohort studies were included: Demers et al. (1991), Loomis (1992), Rosenbaum et al (1994), Stenlund et al. (1997), Cocco et al. (1998), Feychting et al. (1998), Park et al. (2004), Matanoski et al. (1991), Tynes et al. (1992), Guenel et al. (1993), Floderus et al. (1994), Theriault et al. (1994), Savitz et al. (1995), Fear et al. (1996), Johansen et al. (1998), Floderus et al. (1999), Pollan et al. (2001), and Nichols et al. (2005).

Endpoint/type of risk estimation

Type of risk estimation:
  • incidence
(odds ratio (OR))

Exposure

Assessment

Population

  • Group:
    • men
  • Observation period: 1970 - 2002
  • Study location: Sweden, Denmark, Norway France, UK, USA, Korea, Canada

Study size

Total 7,487,222
Other: 356 cases of male breast cancer
Statistical analysis method:
  • heterogeneity test, Funnel plot

Conclusion (acc. to author)

A statistical significant increased risk of male breast cancer with electromagnetic field exposure was found (pooled ORs = 1.32, CI = 1.14 -1.52), and subgroup analyses also showed similar results.
The authors concluded that electromagnetic field exposure may be associated with the increased risk of male breast cancer despite missing experimental evidence.
