Studies of carcinogenicity in mice exposed at least two years to RFR.

Strain, Species, (Sex) Duration Reference	RFR Exposure Level: Frequencies Intensities (Any Other Co-Exposure)	Exposure time No. of Animals	Increased Tumor Incidence (Significance)
B6C3F1 mice (M, F) Tillmann et al., (2007)	902 MHz (GSM) 1747 MHz (DCS) 0.4, 1.3, 4.0 W/Kg	2 h/day, 5 days/week 50/sex/group	Not any increased tumor incidence (NS)
B6C3F1/N mice (M, F) Before birth trough 24 months Wyde et al., (2016)	1900 MHz (GSM, CDMA) 2.5, 5, and 10 W/Kg	9 h/day, 7 days/week 105/sex/group	Not any increased tumor incidence (NS)
B6C3F1 mice (F) 24 months Tillmann et al., (2010)	UMTS fields 48 W/m2 and 4.8 W/m2 + prenatal ENU treatment of 40 mg/kg/b.w.	23.5 h/day, 7 days/week 60/group	Female lung carcinoma and lung tumor rate in ENU-pretreated group (tumor promotion) (p < 0.05)
B6C3F1 mice (F) 24 months Lerchl et al., (2015)	UMTS fields 0.04, 0.4, and 2 W/kg + prenatal ENU treatment of 40 mg/kg/b.w.	23.5 h/day, 7 days/week 96/group	Female lymphoma, lung adenoma and carcinoma, liver carcinoma (tumor promotion) (p < 0.05)
