The same is true of alcohol-based mouthwash and alcohol itself. Anything that routine damages cells is going to be a carcinogen.
Because it's unrelated to the article, doesn't have a source, has multiple typos, and even if it's true, I'm not going to give up hot beverages and food just to avoid (what I assume they're implying to be) a tiny increased mouth and throat cancer risk.
A prospective study of tea drinking temperature and risk of esophageal squamous cell carcinoma https://onlinelibrary.wiley.com/doi/abs/10.1002/ijc.32220
> Previous studies have indicated that hot tea may increase the risk of esophageal cancer. In this large, prospective study, the authors found that drinking hot tea is indeed associated with an increased risk of esophageal squamous cell carcinoma (ESCC). Furthermore, a preference for “very hot” tea more than doubled this risk.
A very-hot food and beverage thermal exposure index and esophageal cancer risk in Malawi and Tanzania: findings from the ESCCAPE case–control studies https://www.nature.com/articles/s41416-022-01890-8
> Thermal exposure metrics were strongly associated with ESCC risk. Avoidance of very-hot food/beverage consumption may contribute to the prevention of ESCC in East Africa.
