The delivery of an electric field, and the present invention provides a system and method and apparatus comprising a selective ablation of solid cancer cells and tumors, resection of selectively or non-thermal target tissue region. A method for delivery of an electric field to the tissue that includes positioning an electrode in the target tissue region, including cancer cells, by applying to the target tissue an alternating current, the method of the present invention, the target cancer tissue region surrounding the electrode and a step of resected non-thermal cells. [Selection Figure Figure 2A本発明は、電場をデリバリし、並びに癌細胞及び固形腫瘍の選択的切除を含む、標的組織領域を非熱的又は選択的に切除する装置及びシステム並びにその方法を提供する。本発明の方法は、癌細胞を含む標的組織領域内に電極を位置決めすることを含む組織に電場をデリバリする段階と、交流電流を標的組織に印加して、電極の周りの標的組織領域の癌細胞を非熱的に切除する段階とを含む。【選択図】 図2A
