A report in the Daily Mail and Mail Online describes the experience of Dr Stephen Allen, a hospital consultant with more than three decades of clinical experience, who says he failed to recognise his own prostate cancer for about two years. The article frames his account as a warning to others to take symptoms seriously and seek medical advice promptly. According to the coverage, Dr Allen later attributes significant longer-term effects to the delayed diagnosis, including changes to his health and sexual function.
Both sources present the same core narrative: a highly experienced physician believes he overlooked signs of prostate cancer in himself for a period of roughly two years, and he reports that the delay has had enduring consequences. The articles do not cite competing explanations for the delay or provide additional independent medical context within the excerpts provided, and they primarily focus on the personal account and the general message about symptom awareness and early evaluation.
