简介：
Overview
Tumor Treating Fields (TTFields) are a noninvasive treatment modality that utilizes low-intensity, intermediate-frequency electric fields to inhibit tumor growth. This study explores the application of TTFields on various cancer cell lines to optimize treatment frequencies and enhance clinical outcomes.
