Primary Care Providers are doctors who have been trained to be a patient’s first point of entry into the health care system. If you're looking to get your annual physical or need to see a doctor about something that's wrong with your health, they’re great resources because they’re trained to be able to diagnose a wide variety of medical conditions. Specialists are doctors who have advanced training and degrees in a particular branch of medicine, such as heart health or bone health. Depending on the field, many can also perform surgery. If you have, say, a suspicious mole, your primary care provider may recommend that you follow up with a dermatologist so he or she can check it out and possibly remove it surgically.
