Abstract
Radiotherapy is a multi-step process that includes planning, contouring, simulation, patient assessment, quality control, and treatment. Each step must be completed before moving on to the next. Numerous factors, including patient characteristics, disease type, management, radiotherapy personnel, equipment, treatment modality, and total/fractional doses, affect the overall duration of radiotherapy. Time is one of life's most valuable resources and should be well managed and utilized. In radiotherapy, eliminating factors that unnecessarily prolong the treatment period significantly benefits the institution, patient, and staff. This review article examines the variables that affect overall treatment time in current external beam radiotherapy routines and offers suggestions for reducing treatment time.
