Scientists have developed a new technique known as hyperthermia therapy, which they hope will allow them to target cancer cells in the body and kill them without harming the surrounding tossed or causing the side effects of chemotherapy drugs and radiotherapy.

Researchers have found they can surround cancer cells with tiny particles of iron oxide that vibrate when in a magnetic field, causing the cells to heat up, reports the Telegraph.
Tests in mice have shown this can raise the temperature of the tumour cells by six degrees above body temperature, around the point when cancer cells start to die.
