heat is byproduct of inflammation triggered intense immune respo

The intense immune response, very often could kill a patient, or in rare cases, could destroy tumors but leave the patient alive - therefore, "SPONTANEOUS CANCER REGRESSION".

However,

using heat alone as cancer therapy practice, will not succeed, even if you have MD Anderson doing the trials;

using heat alone in any cancer theories, will only mislead people.

my friend Mr Nanking can help write an eloquent perspective about this in beautiful chinese language.
