The World Health Organisation announced today that hot drinks probably cause cancer. That does not mean that the hot coffee in your hand right now is going to kill you. This announcement comes with a lot of caveats, and most of us are probably in the clear.

First, a quick reminder about what “probably causes cancer” really means. The WHO’s cancer research group puts items on that list if they “probably” have some kind of link to cancer, even a very small or weak link. Very hot beverages share this list with the pesticide glyphosate, but also with red meat and with shift work that disrupts your body’s sense of night and day. The news on very hot beverages is being published next to an editorial that says just because the WHO calls something carcinogenic, doesn’t mean everybody agrees.
There’s even some good news with this announcement: Coffee and another hot caffeinated drink, maté, are no longer considered carcinogens by the WHO. Coffee actually has health benefits, so it’s totally fine to keep drinking your cuppa. That means that headlines like these, while not incorrect, look a lot scarier than they really are:

The problem the WHO identified is just that drink temperature seemed to increase the risk of esophageal cancer. The evidence isn’t ironclad, either. Here’s how they describe the findings:
This was based on limited evidence from epidemiological studies that showed positive associations between cancer of the oesophagus and drinking very hot beverages. Studies in places such as China, the Islamic Republic of Iran, Turkey, and South America, where tea or maté is traditionally drunk very hot (at about 70 °C), found that the risk of oesophageal cancer increased with the temperature at which the beverage was drunk.
In experiments involving animals, there was also limited evidence for the carcinogenicity of very hot water.
“Smoking and alcohol drinking are major causes of oesophageal cancer, particularly in many high-income countries,” stresses [IARC director Christopher] Wild. … The proportion of oesophageal cancer cases that may be linked to drinking very hot beverages is not known.
How hot is “very hot”? The WHO’s temperature of 70C is within the range that coffee shops typically serve. By the time your drink cools down, though, it’s probably below that. CNN reports that Americans and Europeans don’t usually drink beverages hot enough to be considered higher risk. If you want to be sure of your drink’s temperature, though, consider adding some milk.

I think with how often these tools release something like this, its easier and quicker to say what DOESNT cause cancer,
Every day that goes by, Idiocracy is becoming more and more real, thanks sheep
The following is a list of things that probably definitely don’t give you cancer:

Thank you, that is all.
lol, see how easy that was!
your a natural mate 😉
Who cares. Gotta die of something hey.
I’d rather live a life where I get to enjoy things and maybe possibly get cancer one day over a life avoiding everything and still maybe possibly get cancer anyway
Once you’ve experienced the icy fear of a cancer diagnosis, when you wish you had done EVERYTHING differently, you will know how shallow your remark is.
Was mostly in relation to hot beverages. But I fully understand your sentiment
