These surgeons are highly specialized and in high demand, performing surgery on the digestive tract, skin, breasts and hernias. Sub-specialties include trauma surgery, laproscopic surgery and vascular surgery.
"Surgery is intensely rewarding -- to be able to tell a patient that a family member has a chance at a new life or to rid someone or cure someone of a disability, it's a very rewarding experience," says Marty Makary, a surgeon at Johns Hopkins Hospital.
"It is a lot of training, but I think it's worth it," he adds, although he cautions: "It's important not to give up a lot of things that are important in life early on. Many people defer living life until they're finished all their training, and they do miss out."
