A teenager who was told two months ago that he had just three days to live has astounded medical professionals.

Deryn Blackwell, 14, from Watton in Norfolk, is the only person in the world to have been diagnosed with both leukaemia and another rare form of cancer.

Two months ago after contracting another disease which attacked his immune system, he was told by doctors he would die before the new year.

Deryn was sent to an end of life hospice where doctors and his family prepared him for the worst. But now his body is fighting back and has started to produce red blood cells.
