ABSTRACT

PURPOSE: The study was designed to verify effects of aromatherapy on depression, anxiety and the autonomic nervous system in breast cancer patients who are undergoing adjuvant radiotherapy. METHODS: Data were collected from November 2006 through March 2007 at the C university hospital in Seoul. The study included 33 patients and they were assigned to three groups. Group I had aroma oil inhalation for 2 minutes per time, three times a day for six weeks whereas Group II and a control group inhaled aroma oil for 2 minutes per time, once a day for six weeks. For Groups I and II, a mixture of lemon, lavender, rosewood and rose essential oils were used while control group inhaled tea tree oil. RESULTS: Depression was significantly decreased in patients in the experimental groups only. In Groups I and II patients, anxiety level was lower than that in control patients. Patients in Groups I and II also showed stronger physical resistance to stress than control group patients. CONCLUSION: Aromatherapy should be considered as a method that can significantly decrease depression in breast cancer patients who are undergoing adjuvant radiotherapy.
