Royals Prince William Just Followed in Mom Princess Diana's Footsteps with This Emotional Trip In 2007, William became president of The Royal Marsden NHS Foundation Trust, a position his mom once held By Monique Jessen Published on July 4, 2019 09:35 AM Share Tweet Pin Email On the week of Princess Diana’s birthday, Prince William visited a cancer hospital close to his mother’s heart. Arriving at the Royal Marsden hospital in Chelsea on Thursday morning, William smiled broadly as he greeted staff, and learned about the emotional and psychological support offered at the renowned cancer hospital, a key aspect of treatment. In 2007, William became president of The Royal Marsden NHS Foundation Trust, which operates the hospital. In doing so, he followed in the footsteps of his mother, who became president in 1989. Over the years, he has made multiple trips to the hospital: He worked for two days at their children’s unit back in 2005 and earlier this year he donned blue scrubs to watch two operations being performed using state-of-the-art robotic surgical technology.

He heard first-hand how cancer can have a devastating psychological effect on both patients, their families and even staff members.
