2. What a doctor do Doctors examine people, listen to them describe their health problems, and do tests to see what is wrong. There are many kinds of doctors. Family and general practitioners are often the first doctors that people go to when they get sick. These doctors treat common problems. They also send patients to other doctors, called specialists. Specialists are experts in different types of health problems.

Specializations take many years of practice and examinations but it is worth it if you are passionate about a certain field. Why to Choose Doctor Job

19. BLS expects the number of jobs for physicians to grow faster than the average for all occupations through the year 2016. This is partly because new machines and tools are letting doctors treat more health problems. And it is partly because people are living longer and need more healthcare. Job opportunities for doctors are expected to be good, especially in rural and low-income areas. Some of these areas do not have enough doctors. What about the future?

Countless new discoveries are making their impact on medical practice, and doctors now qualifying will see even more dramatic changes in the future, with the development of many new therapies, involving not only drugs, but also treatments arising from research in electronics, nuclear physics, genetics and molecular biology.
