Head of Urology, Declan Cahill, has performed his 2,000th robotically assisted prostate procedure.
A “radical prostatectomy” involves the removal of the prostate gland and some surrounding tissues in men with advanced prostate cancer.
A typical UK prostate surgeon will carry out around 40 such procedures per year.
Mr Cahill uses a system called the “da Vinci S” to carry out his procedures.
The Marsden was the first hospital in England to introduce it.
