Medical education is a condition of acquiring medical knowledge and not practicing surgical treatment. It is an education or training undertaken to become a practitioner or a typical doctor. The initial training for the purpose of acquiring medical education is taken at medical school. Medical science as we know as began 300 years back. Medicine is a science that aims to prevent or treat the disorders that affect the human body. Medical education varies from country to country. Medicine has many branches; perhaps all the doctors cannot be expert in all of them. By law, a medically acclaimed doctor must complete a period of training before he or she is qualified to diagnose and treat patients. This involves at the very least three years of study, followed by work as a trainee in a hospital. In most countries, a national register lists those doctors who are qualified and are eligible to practice.
