How are doctors trained and certified to treat cancer patients?
When choosing a doctor for your cancer care, you may find it helpful to know some of the terms used to describe a doctor’s training and credentials. Most physicians who treat people with cancer are medical doctors (they have an M.D. degree) or osteopathic doctors (they have a D.O. degree). The basic training for both types of physicians includes 4 years of premedical education at a college or university, 4 years of medical school to earn an M.D. or D.O. degree, and postgraduate medical education through internships and residences. This training usually lasts 3 to 7 years. Physicians must pass an exam to become licensed (legally permitted) to practice medicine in their state. Each state or territory has its own procedures and general standards for licensing physicians.
Specialists are physicians who have completed their residency training in a specific area, such as internal medicine. Independent specialty boards certify physicians after they have fulfilled certain requirements. These requirements include meeting specific education and training criteria, being licensed to practice medicine, and passing an examination given by the specialty board. Doctors who have met all of the requirements are given the status of “Diplomate” and are board certified as specialists. Doctors who are board eligible have obtained the required education and training but have not completed the specialty board examination.
After being trained and certified as a specialist, a physician may choose to become a subspecialist. A subspecialist has at least 1 additional year of full-time education in a particular area of a specialty. This training is designed to increase the physician’s expertise in a specific field. Specialists can be board certified in their subspecialty as well.
