A survey of cancer patients undergoing a radical course of radiotherapy to establish levels of anxiety and depression.
This research aims to establish the prevalence and aetiology of anxiety and depression in cancer patients 
within their first 2 weeks of a radical course of radiotherapy. Depression followed by anxiety is the two 
most frequent psychological disorders experienced by cancer patients. However, these two disorders are frequently undiagnosed and untreated in patients undergoing a course of radiotherapy possibly because the treatment side effects often simulate those of anxiety and depression; the consequences of this can be reduced patient prognosis and increased health care costs. A questionnaire was administered to a sample of 100 eligible cancer patients and this yielded a 68% response rate. The Hospital Anxiety and Depression (HAD) scale was integrated into the questionnaire to accurately establish levels of anxiety and 
depression in the respondents of the study. The study identified six respondents with clinically significant 
levels of anxiety (9%) and six with depression (9%); 21% (n ¼ 14) of participants had higher than normal levels of anxiety and 21% for depression (n ¼ 14). Correlations were then identified between levels of psychological distress and the four independent variables; age, diagnosis, adjuvant medication and pain. Four predisposing factors were established—breast cancer diagnosis, age range 40"50 years, the presence of pain and adjuvant chemotherapy regimes
