This study aimed to investigate circadian rhythm patterns in cancer patients.<h4>Methods</h4>In this cross-sectional study, 150 cancer patients admitted to the hospital enrolled the study during the fall of 2022. The demographic characteristics of patients were collected using a checklist. Patients also completed a morningness-eveningness questionnaire (MEQ). Utilizing Analysis of Variance (ANOVA) and Fisher's exact test, circadian rhythm types with continuous and categorical variables were compared.<h4>Results</h4>The mean age of the study's participants was 49.83 ± 14.53 years.
