Qualifications
Hope you didn't have any plans for the next eleven to sixteen years. After getting your bachelor's degree, it's on to four years of medical school, followed by up to eight years of internship and residency before you can finally put "surgeon" on your business cards.
You must also pass the United States Medical Licensing Examination (USMLE) before you can become licensed. If someone on your operating table asks to see your license and you don't have one, you may be in even more trouble than he is. And he's got a malignant skin mass.
