That hot drinks cause oesophageal cancer has been known since 1998 - I was working in green tea research in the early 2000s and read this article back then. From the abstract:
There were 440 oesophageal cancer deaths during the period from January 1966 to December 1981. Person-years at risk were 3,065,182 in total. Rate ratio and 95% confidence interval adjusted for attained age, prefecture, occupation and sex were (RR (95% CI)): 1.6 (1.2-2.0) for hot tea (drinking green tea at high temperatures) in comparison with not-hot tea (drinking green tea at moderate temperatures); 2.4 (1.8-3.1) for daily (4 times/week or more) alcohol drinking in comparison with non-drinking; and 2.3 (1.7-3.1) for heavy smoking (15 cigarettes/day or more) in comparison with non-smoking.
So they found that hot tea increased the risk by 1.2-2 times, which is not completely out of line with this study - the Japanese study was 220 thousand people, and this one was almost a million, and it’s in a different country at a different time, so there will be other factors.
It’s not about “hot beverage” vs “cold beverge” - the Japanese study that I linked showed that people who drank their tea very hot got more oesophageal cancer than those who drank it at a moderate temperature. Same with this newer study: “Consumption of drinks at a ‘very hot’ versus ‘warm’ temperature was associated with a threefold greater SCC risk but not with AC risk, after adjustment for consumption frequency”

I wonder if there is contributing comorbidities involved. Cause I know I reach for a cigarette with my morning coffee.
I don’t see what connection that would have with the temperature of the beverage.
I drink coffee. Coffee is a hot beverage. When I drink coffee, I want to smoke a cigarette. I am not the only person like this.
So I wonder if there is a selection bias towards people who smoke.
