Cancer has become the leading cause of death in rich nations, overtaking heart disease, according to the results of two landmark, decade-long global surveys of health trends released on Tuesday.
Heart disease remains the leading cause of mortality among middle-aged adults globally, accounting for more than 40 per cent of deaths, the data showed.
It was thought to have been responsible for around 17.7 million deaths in 2017.
