Hyperthermia therapy is a treatment used in battling cancer by heating tumors. The Heating is about as warm as a hot tub. Research has shown that heat can damage or kill cancer cells in some tumors while also making radiation and chemotherapy more effective.
While it has been known for hundreds of years that fevers can kill cancer, only recently has technology been developed that can control and focus heat specifically on tumors.
Local hyperthermia treatment (heat applied to a very small area, such as a tumor) is a well-established cancer treatment. Primary malignant tumors have a bad blood circulation, which make them more sensitive to changes in temperature.
