Magnetic fluid hyperthermia (MFH) is a promising new cancer treatment that essentially 'fries' cells inside tumours. The procedure has been used successfully in prostate, liver, and breast tumours. Magnetic nanoparticles (each billionths of a metre in size) are injected into the body intravenously and diffuse selectively into cancerous tissues. Add a high-frequency magnetic field, and the particles heat up, raising the temperature of the tumour cells...
