## Penetrating and heating The essence of the method developed by scientists at University College London is that 2 mm magnetic balls made of a metal alloy are implanted into the human body. These balls are controlled by the magnetic field of the MRI scanner, which guides them towards the tumor. Once they reach their destination, they are heated and destroy the cancer cells. Because the effect is targeted, nearby healthy cells are minimally affected. ## The soft alternative Researchers believe the method would be effective in treating hard-to-reach glioblastoma, [prostate cancer](https://ul.orna.me/KOge/librarydisease?id=133), and other types of [cancer](https://ul.orna.me/KOge/librarydisease?id=39). So far, successful experiments have only been conducted on mice, but soon, the new method of treatment will be tested on humans as well. Professor Mark Lithgow, one of the authors of the method, says: "MINIMA is a new therapy controlled by an MRI scanner that will avoid traditional side effects by targeting the tumor without harming healthy tissue." ## Undeniable benefits This method of using an MRI scanner allows visualization of the therapeutic seed (metal balls) and the tumor itself throughout the procedure, providing highly accurate treatment. MINIMA will allow for no open surgery, which will reduce patient recovery time and minimize the possibility of side effects. Tests on mice showed that 10 days after the procedure, the tumor size was significantly reduced, and in some cases, the tumor completely disappeared after a month. No drugs were used! MRI scanners are readily available in hospitals around the world and play a key role in the diagnosis of diseases such as cancer. Thanks to this innovative method, the MRI scanner may soon be transformed into a universal platform that can provide not only accurate diagnosis but also effective cancer treatment.
