An apparatus for selectively destroying dividing cells (10) in living tissue, the dividing cells (10) having polarizable intracellular members (24, 26), the apparatus comprising: first and second electrodes (28, 32), wherein the first and second electrodes (28, 32) are disposable in a vicinity of the living tissue to be treated; and an electric field source for applying an alternating electric potential across the first and second electrodes (28, 32) to generate an alternating electric field, wherein the electric potential provides a nonhomogeneous electric field in dividing cells (10) in late anaphase or telophase having electric field lines which generally converge at a region of a cleavage furrow (22) of the dividing cells (10) and define an increased density in electric field thereat, the non-homogenous electric field produced within the dividing cells (10) causing the intracellular members (24, 26) to move toward the cleavage furrow (22) until the intracellular members (24, 26) disrupt the cleavage furrow (22) and cause destruction of the dividing cells (10). |
