Bacon – eat at your own riskFlickr via Creative Commons

It's not just bacon, cigarettes and alcohol that will give you cancer – formaldehyde and leather dust will kill you too.

Earlier this week the World Health Organisation announced that bacon and other processed meats give you cancer. Eating 50g every day increases the risk of colorectal cancer by 18%, the IARC (WHO's cancer-specific agency) said.

With that in mind, here are the 116 things classed as carcinogenic to humans by the IARC.
