Whenever the field of medicine is mentioned, people generally think about doctors and nurses. In fact, not that many years ago, those medical practitioners just about covered the subject. In recent years, however, the field has grown beyond imagination.Specialization in the medical profession has produced a need for many trained personnel in specific areas. Even physicians have specialized in one field because over the past few decades the amount of knowledge in medical practice has become so vast that one person cannot know everything.Unfortunately, this trend has produced an overabundance of specialists and a shortage of primary healthcare physicians (General Practitioners). As the medical field grew, there arose a need for more support staff in hospitals, doctor's offices, and related areas. Whole careers sprang up in the healthcare profession from Medical Billers to Patient Advocates.
