Enhancing hyperthermia treatment for breast cancer using nanoparticles

Abstract:

Hyperthermia treatments involve raising the tumor temperature without damaging the surrounding normal tissues. A novel hyperthermia treatment using nanoparticles within the tumor is presented here. Iron oxide nanoparticles are found to be good absorbers at 2.45 GHz. Under this treatment, the tumor's temperature reached 42°C without damaging the normal tissue. Varying the size and the density of nanoparticle, different temperatures can be obtained. Also, the specific absorption rate increases significantly into the tumor and remains low in the surrounding normal tissue. © 2013 IEEE.
