When doctors at a hospital in Cornwall carried out a follow-up check last summer on a 61-year-old man recently diagnosed with cancer, they found something extraordinary.
The tumours, which scans just a few weeks earlier revealed were littering his torso, had almost gone.
The patient, who was unnamed but was featured in a paper in the British Journal of Haematology, had not yet started chemotherapy for the disease, called Hodgkin lymphoma — a type of blood cancer that affects about 2,100 people a year in the UK.
