The NHS is expected to decide on the future location of south London’s children’s cancer centre this spring.

It comes after a decision that specialist children’s cancer treatment services must be on the same site as a paediatric intensive care unit.

The Royal Marsden in Sutton does not have a paediatric intensive care unit, meaning a small number of children are transferred safely by ambulance to St George’s in Tooting every year.

In 2026, the NHS is either moving the entire site to St George’s, or transferring it all to Evelina London Children’s Hospital in Lambeth.
