The company's principal activity is to develop, produce, market and service microwave systems used for the treatment of cancer and other benign diseases. It has developed the technology required to approach hyperthermia therapy through three techniques: superficial hyperthermia, interstitial or intercavitary hyperthermia and deep hyperthermia. Superficial hyperthermia systems are used to non-invasively treat tumors within a few centimeters of the surface of the body, typical in conditions of melanoma and recurrent breast cancer. Interstitial hyperthermia is primarily used to treat tumors in combination with popular interstitial and intercavitary ionizing radiation therapy. Deep hyperthermia is used to non-invasively treat tumors deep within the body, including many problematic cancer sites located in the pelvis, abdomen and chest areas.
