Cryoablation suppresses lung cancer cell proliferation in mouse models. A, B Tumor volume measurements in each group following cryoablation for 14 days, n = 5 mice per group. Statistical significance was assessed using one-way ANOVA. *P < 0.05, **P < 0.01. C HE staining results of tumor tissue 14 days post-cryoablation exposed changes in the Cry group, with cells appearing smaller and rounder, with condensed nuclei, dense chromatin, and displaying apoptotic morphology. D, E Cryoablation downregulated Ki-67 expression in lung cancer tissue. n = 3 mice per group. Statistical significance was assessed using one-way ANOVA. *P < 0.05, **P < 0.01
