Mother warns it is only a matter of time before a child dies

A mother has warned it is only a matter of time before a child dies - after her son developed the tell-tale symptoms of lymphoma when their car began leaking deadly exhaust fumes. Dr Sophie Duggan, 50, from Amersham, Buckinghamshire, was driving down a country road in 2013 when their exhaust came loose and they booked their car in for a repair.
