There is no clear answer whether and how long it will take for cancer to develop after eating hot food for a long time. Long-term consumption of hot food will generally cause more damage to oral mucosa, esophageal mucosa and gastric mucosa, and it is possible to induce cancer by long-term consumption of hot food. However, the occurrence of cancer is related to many factors and is rather complicated. For example, the etiology of esophageal cancer is generally considered to be related to nitrosamines, long-term smoking and drinking, genetic factors and poor dietary habits, including consumption of overly hot food, etc. However, it is uncertain whether or how long long-term consumption of overly hot food will cause cancer. It is recommended to develop good eating habits and diet, try not to eat too hot, too hot, fried, smoked and pickled food, eat less spicy and stimulating food, eat more fruits and vegetables, and eat regularly; maintain a relaxed mood and regular habits of life and rest; avoid overwork; and strengthen exercise to enhance resistance.
