A teenage cancer patient who last week celebrated her recovery from a brain tumour has been told that she was accidentally given 17 potentially fatal radiation overdoses.

Lisa Norris, 15, received an overdose every time she had radiotherapy at a renowned cancer hospital.

The blunders were blamed on human error and it may be several months before she learns how much damage has been done. She may suffer brain damage or paralysis and has been told that the mistake could prove fatal. (Telegraph)
