Fergie and Beatrice open teen cancer ward in Sutton
Sarah Feguson and Princess Beatrice of York opened a state-of-the-art teenage cancer unit.
The mother and daughter took a tour of the Royal Marsden Hospital and spent time speaking to patients on Tuesday.
Patients showed them to the pool table and Princess Beatrice joined in before spending some time in a "chill-out" pod.
The visit ended with the pair unveiling a plaque on the roof terrace with patients.
Mrs Ferguson said: "The whole reason we are here today is for these guys.
"We are very pleased to open the Teenage Cancer Trust unit here in Sutton, thank you."
After 27 months of construction, three year’s worth of fundraising gathering £3.5million, the new 13 bed Teenage Cancer Trust unit was officially opened.
The unit will support 16 to 24 year olds from across Sussex, Surrey and Kent in their fight against cancer.
Patient, Sarah Campbell, 18, from Bexhill, was diagnosed with leukaemia when she was seven. The cancer has been treated but she still receives treatment from the outpatient centre at the hospital.
On Tuesday she chatted with the special guests and said: "I was treated mainly in the old unit.
"When I was seven it was fine because I was obviously a child but when I was 12 I found it kind of hard because I was in between a child and being a teenager.
"I did want to do paintings and drawings but I also wanted my own space and to watch movies and DVD’s.
"So this is just amazing for anybody having treatment."
She is currently at college and plans to study therapeutic radiography in the hope she can treat people at the Royal Marsden.
Another, Richard Storry, 19, said: "They were very good sports - none of us actually knew how to play pool - we probably should have stuck with jenga.
"They are really nice down to earth people."
