OBJECTIVE: This study was conducted to observe the effect of progressive relaxation exercises on anxiety and comfort level of breast cancer patients receiving chemotherapy. MATERIALS AND METHODS: A control group pre-test/post-test quasi-experimental model was applied with experimental (30) and control (30) groups, who agreed to participate in this study. Data collection was with the "Personnel Information Form, State-Trait Anxiety Inventory and General Comfort Scale". RESULTS: The average age of the patients that participated in the study was 49.1±7.96 years. Eighty-three point three percent (n=25) of the patients in the experiment group and 86.7 (n=26) percent of patients in control group were married. Patient state of anxiety post-test mean scores were 36.2±8.21 in the experimental group and 43.4±7.96 in the control group, the difference being statistically significant (p<0.05). The general comfort scale post-test mean scores were 149.5±13.9 in the experimental group and 137.7±15.0 in the control group, again statistically significant (p<0.05).
