Medical law is the term for law that applies to the medical profession. If you want to work in that field, either attend law school or become a paralegal. Or, you can approach it from the medical side of things, become a registered nurse and then attend law school or become a paralegal. Medical law would include cases of alleged medical malpractice, faulty medical equipment, or contracts.
Medical law is a branch of law that deals with medical problems and other legal problems. You can study the course at schools such as University of Maryland, Drexel University, Hamline University and Duke University.
If you are studying to become an attorney, you would first need to take basic courses in law. Medical malpractice and/or personal injury are types of "medical" law or an area of law an attorney "specializes" in. The same would apply for a criminal attorney, a defense attorney, etc.
