ABSTRACT
Sleep disturbances (SDs) can be defined as any symptom or condition that interferes with normal sleep. SDs in the cancer population can present as a temporary symptom associated with the cancer or as part of depression or anxiety disorders, and physicians often assume that the SDs will resolve when the underlying problem is treated. The most important aspect during assessment of SD in cancer patients is characterizing the sleep difficulty and identifying the causes, exacerbating factors, and comorbidities that trigger the SD. Several screening and evaluation tests are available for detecting and diagnosing SD. Laboratory investigations may be considered when associated medical conditions are causing SD. Management of the underlying pathology is paramount in order to lessen the somatic, psychological, and social effects of SD experienced by cancer patients. Patients receiving palliative care but who maintain a relatively better prognosis and have minimal comorbid conditions will likely tolerate pharmacological treatments for insomnia similar to medically healthy individuals.
