The first clinic of its kind in Europe has opened at Addenbrooke's Hospital in Cambridge with the aim of finding a cure for one of the rarest types of cancer.
PAWS-GIST mostly affects young women. It generally starts in the stomach with several primary tumours.
The first patient at the new clinic was Rachel Gilbert, 28 - the first person in East Anglia to be diagnosed with the cancer when she was 15.
