Abstract
A light generating circuit is implanted in a subject's body and aimed at a target region such as a tumor. A photosensitizer is introduced into the target region, and an AC electric field is induced in the region. The field causes the light generating circuit to generate light, which activates the photosensitizer; and at certain field strengths and frequencies, the field itself has a beneficial effect. The beneficial effects of the field and the activated photosensitizer are thereby obtained simultaneously.
