IARC: 116 things that can cause cancer
The International Agency for Research on Cancer – a body that collects and publishes cancer figures worldwide – has a list of the 116 substances and activities (for some of them are more verb than noun) that are now considered to cause cancer.
Red meat isn’t on the list – that only probably causes cancer. This is the IARC’s group 1 list – the stuff it says definitely is carcinogenic. The IARC splits the list into three categories, which it calls “exposure circumstances”, “mixtures” and “agents”.
