When looking for a doctor for yourself or your family, you will typically only need a general practitioner. However, doctors may attend different types of medical schools, so knowing your doctor's credentials and approach to medicine will help you make the best choice. In some cases, you may even need to seek a doctor who specializes in a certain type of medicine, such as surgery or oncology.
