A tiny magnetic seed could hold the key to treating tumors in some of the most inaccessible parts of the body. According to Sky News, minimally invasive image-guided ablation, or "Minima", is a new therapy which sees the 2mm seed guided through the brain to heat and destroy tumors.
Tested on mice, it involves using an MRI scanner to navigate the seed's path to the tumor, before heating it remotely and using this heat to kill off the cancer cells. The technique could mean more effective treatment, reduced recovery times, and less chance of side effects.
