The global burden of cancer.

The global burden of cancer is increasing. By 2020, the global cancer burden is expected to rise by 50% owing to the increasingly elderly population. The delivery of cancer care is likely to increase the need for perioperative physicians for both operative procedures and pain management, offering new professional challenges. Specifically, these challenges will include volume and financial management, as well coordination of cancer treatment and pain management. Coordinated, team-based cancer care will be essential to ensure value-based care. Short and long-term outcome measurement is an integral part of the process.
