Cancer is the result of intrinsic genetic mutations in human cells. Water, upon entering the digestive tract, participates in bodily fluids, blood circulation, and other fluid systems, without causing deep-level effects on genes. While some studies suggest that cancer cells indeed exhibit a "fear of high temperatures," the oral and intestinal mucosa of normal individuals have a tolerance to temperature, generally between 40-60 degrees Celsius.
The World Health Organization has long categorized temperatures above 65 degrees Celsius as Class 2A carcinogens. Compared to the implausibility of high-temperature cancer prevention, the potential harm of hot water to the human body is more significant. Moreover, even if hot water enters the body, it will be cooled down by the body's own temperature regulation system, making it impossible to reach the so-called "high-temperature state" at the affected site.
