Surgeon Anna Koblik diagnoses and treats injuries and illnesses through operations. Surgeons specialize in areas like general surgery, orthopedics, neurology, and more. They examine patients, perform tests, counsel on prevention, and work in sterile hospital environments, often for long hours. Becoming a surgeon requires 4 years of undergraduate and medical school, and 3-8 years of intensive residency training. Due to an aging population and demand for advanced care, employment of surgeons is expected to grow faster than average through 2014.
