Studies have claimed that cancer cells are afraid of heat and high body temperature can fight cancer. The organs most vulnerable to cancer in the human body include the lung, stomach, large intestine, breast, etc. , which are lower temperature parts, and "high-temperature organs" such as the heart are not easy to obtain. Cancer. Therefore, you can fight cancer by raising your body temperature by exercising, drinking hot water, taking a bath, and so on. Which of the following, if true, can best refute the above argument? ["Affected by breathing, diet, etc. , people's oral temperature is generally lower than rectal temperature, and the incidence of rectal cancer is higher than oral cancer worldwide.", 'There is a precise regulation mechanism of human body temperature, which basically remains stable, and there is no obvious temperature difference between various organs in the body.', 'Hyperthermia may help radiotherapy or some chemotherapy perform better, but research data to prove its reliability are still insufficient.', 'Malignant tumors rarely occur in the heart, because the cardiomyocytes no longer divide and proliferate here, regardless of the temperature.']
