Cancer cells are more sensitive to heat than normal cells and hyperthermia takes advantage of this to weaken them and make them more sensitive to other treatments by increasing the temperature, either of the whole body (full-body hyperthermia) or of the part of the body with the cancer (localized hyperthermia). Using modern electromagnetic heating methods this can be carefully controlled and targeted to trigger cancer cell death without causing significant side effects.
When combined with radiotherapy, research shows hyperthermia has a complementary and additive effect. Extensive research also shows that hyperthermia improves the efficacy of many chemotherapeutic agents.
At the same time hyperthermia has been shown to support the immune system in forming an effective immune response to the cancer.
