“…Equivocal evidence of carcinogenicity of GSM-modulated cell phone RFR at 1900 MHz was observed in male B6C3F1/N (combined incidences of fibrosarcoma, sarcoma, or malignant fibrous histiocytoma in the skin and combined alveolar/bronchiolar adenoma or carcinoma of the lung) and T A B L E 7 Incidence of animals bearing atypical precursors or mammary adenocarcinomas and haemolymphoreticular neoplasias (HLRN) compared to 0.1 Gy positive control in male (M) and female (F) Sprague Dawley rats exposed to S-50 Hz MF and/or γ radiation 19 The results of the NTP study on rats motivated the Ramazzini Institute to publish the early results of its study on 1.8 GHz GSM dealing with the evaluation of the preneoplastic and neoplastic lesions of the heart and of the brain. 22 The experiment encompasses three groups of 817, 811 and 411 male and female Sprague Dawley rats exposed, respectively, to 5, 25 and 50 V/m for 19 h/d from prenatal life (exposing the female breeders from the 12th day of pregnancy) and continuing the exposure of the offspring until natural death. A fourth group of 412 male and 405 female rats served as controls.…”

Epidemiological studies have suggested that human exposure to extremely low‐frequency electromagnetic fields from the electric power and to mobile phone radiofrequency electromagnetic fields induce an increased risk of developing malignant tumours. However, no adequate laboratory data, in particular long‐term carcinogenicity bioassays to support the epidemiological evidence, have yet been available. This motivated the Ramazzini Institute to embark on a first project of four large life‐span carcinogenic bioassays conducted on over 7000 Sprague Dawley rats exposed from prenatal life until natural death to S‐50 Hz MF alone or combined with gamma radiation or formaldehyde or aflatoxin B1. Results now available from these studies, which started concurrently, have shown that exposure to Sinusoidal‐50 Hz Magnetic Field (S‐50 Hz MF) combined with acute exposure to gamma radiation or to chronic administration of formaldehyde in drinking water induces a significantly increased incidence of malignant tumours in males and females. A second project of two large life‐span carcinogenic bioassays was conducted on over 3000 Sprague Dawley rats exposed from prenatal life until natural death to 1.8 GHz GSM of mobile phone radio base station, alone or combined with acute exposure to gamma radiation. Early results from the experiment on 1.8 GHz GSM alone show a statistically significant increase in the incidence of heart malignant schwannoma among males exposed at the highest dose.
