1. A system for treating cancer cells in a target body area of a patient comprising:
an alternating polarity (AP) magnetic field generator;
at least one AP electromagnetic coil coupled to the AP magnetic field generator and adapted to be coupled to the target body area; and
a controller for controlling the AP magnetic field generator and the at least one AP electromagnetic coil, wherein the controller is adapted to cause the AP magnetic field generator and the at least one AP electromagnetic coil to generate and apply to the target body area an AP magnetic field having a frequency of 0.5-500 kHz and a field strength of 0.2-5 mT, wherein the AP magnetic field selectively affects the cancer cells to prevent metastasis of the cancer cells, while leaving non-cancer cells substantially unharmed.
