Some studies claim that cancer cells are afraid of heat, and high body temperature can fight cancer. The most cancer-prone organs of the human body, including the lungs, stomach, large intestine, breast, etc., are all parts of the body with low body temperature, and high temperature organs such as the heart are not easy to get cancer. 
Affected by breathing, diet, etc., the temperature of the human mouth is generally lower than that of the rectum, but the incidence of rectal cancer worldwide is higher than that of oral cancer.
 you can  raise your body temperature to fight cancer by doing exercise, drinking hot water, bathing and other ways.
