We are running the Brighton Marathon in April 2023 in memory and celebration of our inspiring friend Natalie Street, who is missed and remembered every day. Nat was treated by the Royal Marsden for 4.5 years prior to passing away from metastatic melanoma in November 2022. She received outpatient and inpatient care, including novel therapies that gave her longer to enjoy life than would have been possible if she were diagnosed five years earlier. Whilst this will never have been long enough, we hope that with continued fundraising the Royal Marsden will keep developing these therapies, supporting patients and moving ever closer to a world without cancer.
