The Beliefs and Knowledge of Patients Newly Diagnosed With Cancer in a UK Ethnically Diverse Population

Abstract 

Aims

To compare knowledge about the outcome of cancer treatment and beliefs about the causes of cancer among British South Asian (BSA) cancer patients of predominantly Gujarati origin with the beliefs held by British White (BW) cancer patients. We also wanted to determine if these beliefs impacted upon the patients’ mental health.

Materials and methods

We administered a questionnaire about cancer beliefs to 94 BSA and 185 BW newly diagnosed cancer patients at the Leicestershire Cancer Centre. Using a Likert seven-item scale, we analysed patients’ views on confidentiality, outcome and cancer treatment and 15 items about beliefs about the causes of cancer. Patients also completed the Hospital Anxiety and Depression Scale, Patient Health Questionnaire, Mini-MAC, Distress Thermometer and newly developed Cancer Insight and Denial, and Physician/Patient Trust questionnaires.

Results

Most (232/279; 83.2%) believed cancer was curable. However, significantly more BSA (10.6% versus 2.7% BW P=0.001) believed cancer was incurable. Although most (86.4%) agreed that smoking can cause cancer, there was a widespread lack of knowledge of the importance of diet and obesity as contributing causes of cancer. There was, in general, an over-emphasis on pollution, stress and injury as important aetiological agents. There was a strong belief in supernatural involvement in the development of cancer among a minority of BSA patients. Twenty per cent of this sample believed that treatment, especially surgery, caused the cancer to spread and this was associated with significant depression in BSAs (P=0.019) and anxiety in both BW (P=0.006) and BSA (P=0.0134) patients.

Conclusion

Our results show that there is a continual need for education about the causes of cancer both in BW and BSA patients.
