Anxiety and depression in Iranian breast cancer patients before and after diagnosis.

A prospective study was conducted to measure anxiety and depression in Iranian breast cancer patients before and after diagnosis using the Hospital Anxiety and Depression Scale (HADS). The HADS was administered at two points in time: before diagnosis and 3 months after. In all, 168 breast cancer patients were interviewed. While 48% of patients had severe symptoms of anxiety at both baseline and follow-up, more than 60% of patients had no symptoms of depressive illness at pre-and post-diagnosis assessments. Comparing anxiety and depression before diagnosis and after 3 months, there were no significant differences between patients' scores on anxiety (P = 0.42) and depression (P = 0.98) subscales. The results showed that patients with advanced disease and a lower performance status were more anxious and experienced more depression. The study findings suggest that severe symptoms of anxiety are the most frequent symptoms in Iranian breast cancer patients. It seems that during the process of diagnosis and 3 months after psychological morbidity persists in patients who suffer from breast cancer.
