Sleep and Cancer compiles novel information on the interactions between sleep and cancer. The book highlights how prevention and treatment of sleep disturbances in clinical cancer practice helps prevent the onset of tumors and their comorbidities, both short- and long-term. It analyzes how sleep disorder treatment improves the response to antitumor therapy in the long term, presenting procedures regarding cognitive-behavioral therapy of sleep disorders that are often overlooked in the oncological field. In addition, the book suggests new therapeutic approaches in oncology that are based on the knowledge of sleep mechanisms, such as chronotherapy, use of melatonin as an adjuvant in chemo- and radiotherapy, and orexinergic drugs.
