Abstract
A method of treating abnormal cells, including cancer cells, includes administering a photosensitive chemical substance to accumulate at the cancer cell and applying a constant electric field or a high frequency electric field to the abnormal cells to thereby excite the photosensitive chemical substance to undergo a reaction detrimental to the abnormal cells. The abnormal cells may be in tissues inaccessible to light, including cancer cells in the blood.
