Researchers from Tel Aviv University in Israel have begun tests using gold to fight cancer. Tests are currently being conducted on mice, with the primary focus to improve the rate that tumours shrink in the head and neck, especially in the mouth, nose or throat.

The precious metal is known to increase the intensity of radiation, so the hope is that it can be attached to tumours to make radiotherapy more effective. The microscopic amounts of gold are bound to a drug known to attach itself to tumours, which then in turn position it ready for the radiation blasts.

The findings were made early in 2016, and their success has been corroborated by researchers at other universities since then. Preparations are currently being made for human trials, which will hopefully begin later this year.
