TED-Ed: Performing brain surgery without a scalpel | Hyunsoo Joshua No

Stereotactic radiosurgery is a non-invasive procedure that uses focused radiation beams to target and destroy brain tumors without incisions. It begins with imaging techniques like CT and MRI to map the tumor's location and shape. Multiple low-dose radiation beams converge on the tumor, shearing its DNA and creating a hostile environment for cancer cells. This method minimizes damage to healthy tissue and allows for quick recovery. While not suitable for all cases, radiosurgery offers a pain-free alternative to traditional surgery and is being explored for other medical conditions.
