Scientists have discovered an exciting new cancer treatment that uses light to precisely target and destroy cancer cells without harming nearby healthy cells. By using a technique called optogenetics, researchers can activate a death pathway in cancer cells, which not only kills them but also triggers the immune system to fight back. This innovative approach could revolutionize cancer therapy by reducing unwanted side effects and training the immune system to recognize and attack cancer more effectively. The breakthrough, which involves using plant genes to make cells responsive to light, opens the door to more targeted and less harmful cancer treatments.

Cancer treatments that try to kill cancer cells frequently hurt and damage nearby cells and tissues in the process. However, according to a recent study, scientists have found a new way to precisely destroy dangerous cells by directing light toward them.
