Declan Cahill is a urological surgeon. In 2015 he was appointed by The Royal Marsden to augment their prostate cancer diagnostics and surgical service. Prior to this, he spent 12 years as a Consultant Urological Surgeon at Guy's and St Thomas' NHS Trust (2003-2015).

He qualified in 1993 at Charing Cross and Westminster Medical School, now Imperial College, with distinction. He has trained in London: being awarded the Hallett Prize Gold Medal for General Surgery and then the Keith Yates Gold Medal for Urology. After completing his Urology training in London he undertook fellowship training at Institute Montsouris, the world leading Institution at that time, to specialise in minimally invasive prostate surgery. He has strong reputation in general urological diagnostics and treatment as well as his specialist practice in prostate cancer. 

For robotic radical prostatectomy his results are equivalent to the best-published results in the world for cancer margins, continence and potency. He operates on a very high volume number of patients with prostate cancer each year.

The national results for radical prostatectomy within British Urology are to be made public for the first time in 2015. Declan Cahill is the highest volume surgeon with best (lowest) positive margin rates (cancer clearance) within high volume surgeons. 14.8% across all disease stages with a national average of 28.7%.
