Focusing techniques in breast cancer treatment using non-invasive microwave hyperthermia

Different techniques for non-invasive microwave hyperthermia for breast cancer treatment are discussed. Although microwave hyperthermia was presented as a promising tool for cancer treatment, its clinical application is still far from maturity due to the drawbacks of current approaches. Hence, the main proposed techniques are explained in this paper to highlight the advantages as well as limitations of current approaches. A comparison on the system design and focusing techniques for localized heating tumor is then presented. To that end, several possible techniques to improve the focusing of microwave hyperthermia for breast cancer treatment are proposed.
