Some scientists have developed a promising method for targeting and destroying individual cancer cells without harming the tissue around them. Tiny (like nano tiny) gold-plated iron-nickel discs are attached to cancer-seeking antibodies. The antibodies attach themselves to the cancer cells and when an alternating magnetic field is applied, the metal nano-discs vibrate and literally shake the cancer cells to death.
Since the antibodies are attracted only to brain cancer cells, the process leaves surrounding healthy cells unharmed. This makes them unlike traditional cancer treatment methods, such as chemotherapy and radiation, which negatively affect both cancer and normal healthy cells.
