Studies of carcinogenicity in other models 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)
E mu-Pim1 mice (lymphoma-prone) (M, F) 24 months Utteridge et al. (2002)	898.4 MHz GSM 0.25, 1.0, 2.0, and 4.0 W/kg	1 h/day, 5 days/week 120/sex/group	Not any increased tumor incidence (NS)
E mu-Pim1 mice (lymphoma-prone) (M, F) 18 months Oberto et al. (2007)	900 MHz pulse modulated 0.5, 1.4, 4.0 W/kg	1 h/day, 7 days/week 50/sex/group	Not any increased tumor incidence (NS)
E mu-Pim1 mice (lymphoma-prone) (F) 18 months Repacholi et al. (1997)	900 MHz GSM 0.008–4.2 W/kg, averaging 0.13–1.4 W/kg	1 h/day, 7 days/week 100/group	ẞ-cell lymphoma (p < 0.01)
C3H/HeA (breast cancer-prone) and Balb/c mice 12 months (M, F) Szmigielski et al. (1982)	2450 MHz 50, 150 W/m2 Balb/c mice also treated with 3, 4-benzopyrene (BP)	2 h/day, 6 days/week NR	Acceleration of breast tumor developed in C3H/HeA mice Acceleration of BP-induced skin cancer in Balb/c mice (p < 0.05)
