As well as increased clinical space, the refurbishments include a space for carrying out blood tests, a dedicated information hub and a sensitive conversation suite.
Ms Kennedy said: “The new facilities have been designed around patient needs and provide a welcoming environment that is expertly equipped to support individuals and their loved ones.
“The incredible care at Royal Surrey was second to none, their approach enabled me to continue competing whilst on chemotherapy and the team truly understood me as a person, not just a patient.”
During the opening, Ms Kennedy is expected to present the centre with her framed Team GB Lycra that will be displayed in the hospital.
