A comprehensive system for inducing cellular regeneration and/or degeneration processes and methods of treatment based on such processes through generating and applying a sequentially programmed magnetic field (SPMF) to the area to be treated. In the case of regeneration and degeneration of cells, the pulsing frequencies are in the range of about 0.1 to about 2000 Hz based on the indication of the disease type which was determined by either the patient's MRI, CT, Ultrasound or other diagnostic information. Methods for treating diseases or conditions that will benefit from regeneration and/or degeneration of cells. For example, methods for treating cancer, arthritis, neuro degeneration conditions, such as the age-related progressive loss of nerve cells, Alzheimer's, Parkinson's, ALS, and Huntington's disease, retinal degeneration, and other damage to sensory systems (e.g., visual, auditory, somatosensory), in stroke, head and spinal trauma, epilepsy, in drug and alcohol abuse, in infectious diseases, in exposure to industrial and environmental toxicants, and, perhaps, in mental disorders and chronic pain. Methods for treating non-healing fractures and other bone disorders are also disclosed.
