Abstract

An alternating electric field may be applied to a target region in a living body or to cells in vitro. The alternating electric field is applied during a first interval of time that is at least 1 hour long. The first interval of time includes a plurality of (e.g., 10) non-overlapping sub-intervals of time per hour. In each of the sub-intervals of time, (a) the alternating electric field has a frequency between 50 kHz and 1 MHz (e.g., 50-500 kHz, or 100-300 kHz), (b) the alternating electric field has a respective peak intensity of at least 0.1 V/cm in at least a portion of the target region, and (c) the alternating electric field remains at the respective peak intensity less than 75% the time (e.g., 25% or 33% of the time).
