Why are cancer rates rising among younger people? – with Kimmie Ng and Charles Swanton
Episode 47, Sep 12, 05:00 AM
Since the early 1990s, there’s been a concerning uptick in cancer incidence among adults younger than 50 years.
Scientists are racing to understand what’s driving these trends. Some evidence points to roles for established risk factors – including smoking and obesity. But some research is also exploring environmental exposures – such as microplastics and forever chemicals – and asking if these could be changing the microbiome and potentially causing inflammation within the body.
So what do these trends mean for cancer research, for health services and national policy? And faced with such stark trends, where are there grounds for hope?
To discuss, our Chief Executive Jennifer Dixon is joined by:
