The prognostic role of sleep disorders in oncological disorders is still underestimated worldwide. The prevalence of insomnia is highest in breast cancer (42-69%) compared with other localizations (for example, prostate, gynecological diseases, head and neck, urinary tract or gastrointestinal tract, etc.) [3]. Breast cancer patients are prone to chronic insomnia for a range of individual reasons, for example, severe somatic discomfort and pain with a tendency to catastrophize, hot flashes, paresthesia, endocrine therapy and other hormonal changes associated with breast cancer treatment generate a range of fears, including dysmorphophobic experiences.
