Drinking very hot liquids can injure the lining of the mouth and throat. Some research has associated regularly consuming very hot beverages with an increased risk of esophageal cancer, particularly in certain populations.
This evidence should not be misrepresented as proof that ordinary hot tea causes throat cancer. Allowing beverages to cool to a comfortable temperature is a sensible way to reduce the risk of thermal injury.

These habits do not all carry the same level of evidence for throat cancer, and none can establish the cause of an individual's diagnosis. Tobacco and alcohol are established risk factors; persistent symptoms require assessment rather than assumptions about their cause.
Chapter 3: The Established Causes and Risk Factors of Throat Cancer
Throat cancer develops when cells acquire changes that allow them to grow abnormally and evade the body's normal controls. These changes usually accumulate through a complex process rather than appearing because of one specific meal or morning routine.
Tobacco is one of the most important preventable risk factors for many cancers of the head and neck. Cigarettes, cigars, and other tobacco products expose tissues to substances that can damage DNA. Secondhand smoke also has health consequences, although the risks differ according to the type and extent of exposure.
Alcohol is another established risk factor. When alcohol is metabolized, acetaldehyde can damage DNA and interfere with normal cellular processes. People who both smoke and drink heavily face particularly elevated risks for several head and neck cancers.
HPV is associated with many cancers of the oropharynx, which includes parts of the throat near the tonsils and base of the tongue. HPV-related oropharyngeal cancer differs in important ways from some tobacco-associated cancers.
Other factors may include certain occupational exposures, previous radiation exposure, age, and individual medical history. The importance of each factor depends on the specific cancer location.
