Abstract: A method and apparatus for therapeutically treating cancer is provided. The apparatus includes a magnetic field generator for producing a controlled, fluctuating, directionally oriented magnetic field parallel to a predetermined axis projecting through a malignant neoplasm. In one aspect, a field detector measures the magnetic flux density along the predetermined axis. The applied magnetic field may comprise a full-wave rectified signal oscillated at predetermined frequencies to maintain a preselected ratio of frequency to the effective flux density, where the ratio regulates the growth characteristics of cancer cells of the neoplasm. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field after nulling out the local magnetic field at that region containing the neoplasm.

Abstract: A method is provided for enhancing the transport of a selected ion having a predetermined charge-to-mass ratio through a biomolecular membrane located in a space subjected to a local magnetic field. The space defines at least one reference path passing through the membrane in opposite first and second directions. The method includes the steps of creating a magnetic field which, when combined with the local magnetic field, produces a magnetic field having a flux density with at least one component representable by a component vector having a direction extending in the first direction along the path. This component of the magnetic field has a magnitude that fluctuates at a predetermined rate to produce a nonzero average value. A predetermined relationship between the ratio of the selected rate to the nonzero average value and the charge-to-mass ratio of the predetermined ion is thereby created. The predetermined relationship is a function of the cyclotron resonance frequency of the ion.
