The field of medicine concerns itself with diagnosing, preventing, and treating human illnesses and injuries. Medical students learn to heal and care for sick people, using their in-depth knowledge of the human body and topics such as pharmaceuticals and surgery.

A Doctor of Medicine is a highly advanced degree that requires about six years of work. Many M.D. programs require a combination of classwork, research papers, and hands-on clinical practice to certify students as medical doctors.
