The purpose of this study was to explore young British men’s understandings of prostate health and cancer of the prostate. A total of 16 White-British men between 31–50 years of age took part in interviews face-to-face or through computer-mediated communication. Thematic analysis broadly informed by grounded theory identified two key themes; ‘limited knowledge about the prostate’ and ‘early detection & unpleasant procedures’. Accounts are discussed with reference to implications for improving men’s understandings of prostate cancer, and likelihood of self-referral for prostate screening where necessary.
