Black men less willing to be investigated for prostate cancer

2 March 2015

The incidence of prostate cancer among men of Afro-Caribbean origin is higher than in white men, they are more likely to be diagnosed as emergencies and their mortality rates are higher. Until now, it has been unclear why these disappointing outcomes exist. Researchers at the Universities of Exeter, Bristol and College London studied the preferences and choice of more than 500 men who were presented with a realistic hypothetical prostate cancer investigation scenario while attending general practices in Bristol.

Each man was presented with a description of a prostate cancer symptom and estimated risk of the disease. The team found that preference for investigation was lower in black men irrespective of the risk presented in the scenario. This difference was strongest in relation to the scenarios associated with the lowest risk level, with just 44 per cent of black males opting for investigation compared with 91 per cent of white males. In both groups, the most common reason for declining investigation was low risk, but significantly more black men stated that they simply did not want to know if they had cancer. 

The study, published on 2 March in the British Journal of General Practice (BJGP), was led by Tanimola Martins, at the University of Exeter Medical School. Tanimola said: “We know that black men are significantly more likely to develop prostate cancer, and are more likely to die from it. For the first time, this study has found evidence that black men are less willing than white men to be tested for the disease. GPs should be aware of the reduced appetite for testing in black males, which may be linked to fear and a perception that treatment may lead to severe complications. Doctors could consider proactively discussing the subject. Education targeted at the black community and the health professionals who treat them may also help to address this.”

Professor Willie Hamilton, of the University of Exeter Medical School, outlined the next steps. He said: “We know that black people have worse outcomes with other cancers, particularly breast cancer. To address this, we need to understand the reasons behind that, and this could be a significant step on that journey.”

Dr Jonathan Banks, one of the study’s co-authors from the University of Bristol’s Centre for Academic Primary Care, said: “The findings help us understand some of the reasons why black males have a lower preference for investigation in prostate cancer. We hope these findings may lead to new ways to help educate the black community and health professionals about symptoms and the importance of early investigation.”

The research was supported by the NIHR Collaboration for Leadership in Applied Health Research and Care South West Peninsula (PenCLAHRC).
