It notes that most studies have exposure assessment affected by multiple biases, with only a few using detailed individual RF exposure data, and that co-exposure to other occupational carcinogens is likely in many job categories. The authors conclude these issues limit the feasibility of pooled quantitative synthesis.",

  "summary": "This abstract describes an ongoing systematic review of human studies on occupational RF-EMF exposure (3 kHz–300 GHz) and cancer risk. Preliminary findings emphasize heterogeneity in studied job categories and cancer outcomes, and frequent bias in exposure assessment, with only a few studies using detailed individual exposure data. The authors also highlight likely co-exposure to other occupational carcinogens, limiting the ability to perform a pooled quantitative synthesis.",

    "The review targets human studies of occupational RF-EMF exposure and medically diagnosed cancer.",
    "It is conducted under PRISMA guidance and registered in PROSPERO (CRD42020200202).",
    "Included studies cover different cancer types, including brain tumors.",
    "Most studies reportedly have exposure assessment limitations and potential bias.",
    "Only a few studies are noted to use detailed individual RF exposure data.",
    "Co-exposure to other occupational carcinogens is expected in many job categories and may confound results.",
    "Heterogeneity and exposure-assessment bias limit the feasibility of meta-analysis based on preliminary results."
