title: [Geomagnetic field variation in early ontogenesis as a risk factor for oncopathology].
abstract: The data on 534 cancer patients with tumors of 15 different sites were evaluated to elucidate the influence of geomagnetic field (GMF) in certain months of the pre- and early postnatal periods on future incidence of cancer. We identified neoplasms of the breast, lung, urinary bladder, hypophysis, ovary, prostate, liver, Hodgkin's disease, lymphoma and, possibly, gastric cancer as GMF-dependent. This relationship appeared to be idiosyncratic with every cancer variety. It was negligible in cases of esophagus, thyroid, uterine cervix and colorectal cancer. GMF variations as a carcinogenic factor in early ontogenesis can be assessed quantitatively.
