Illustrates the effect on tumor growth of: the 8-day course of gamma irradiation therapy (IR), the daily exposure to the TEMF therapy (TEMF), a combination of gamma irradiation and TEMF therapy (TEMF/IR), and no treatment (Control). The tumors were all 35 mm³ or less at the start of treatment. The growth rate is the slope of the linear regression of the tumor volumes at each time. It can be seen that tumor growth was beginning to deviate from the linear fit about 18 days after the start of TEMF or radiation treatments however there was still a reasonable linear fit. ANOVA was used to determine any statistical differences in growth rates between treatment groups. Different letters demonstrate significant differences. Gamma irradiation alone (IR) or in combination with TEMF (TEMF/IR) reduced the tumor growth. The TEMF therapy resulted in a slower tumor growth rate than the untreated controls but not as slow as the gamma irradiated mice.
