The Duke of Cambridge is to meet patients receiving pioneering new treatments at one of the world's leading specialist cancer hospitals.
William will visit the Royal Marsden NHS Foundation Trust in Sutton, south-west London, for a tour of two research facilities before hosting a private dinner for the hospital's charity.
He will be shown state-of-the-art laboratories at the Centre for Molecular Pathology and meet clinicians and patients taking part in trials at the West Wing clinical research centre.
Later, the Duke will host dinner for The Royal Marsden Cancer Charity at Kensington Palace.
The Royal Marsden was founded as the Free Cancer Hospital in 1851 by Dr William Marsden, and was the first hospital in the world dedicated to cancer treatment and research into the causes of the disease.
The Duke became the Royal Marsden's president in 2007, following in the footsteps of his mother Diana, Princess of Wales who held the same position from 1989 until her death in 1997.
William has had a long association with the hospital, spending two days of work experience at the institution's children's unit in December 2005. He helped out in various departments, including medical research, catering and fundraising, and toured a number of the wards.
In November 2013, he visited the hospital's site in Chelsea, west London, where he viewed sections of a breast reconstruction procedure and the removal of a bladder tumour involving two patients.
The Duke and his wife the Duchess of Cambridge opened the trust's cancer unit for children and young people at its Sutton site in 2011.
