PhD medical student and STEM ambassador, Leo Garcia, shows students how he uses ultrasound to detect cancer tumours.
During his visit to Kingsbury High School in London, he shows the students how an ultrasound scanner works by using it on their teacher in a game called I Spy in Sir.
Leo then shares some basic facts about cancer and explains how cancerous tumours grow. He also uses a sorting game with the students, to help them understand elasticity and how it relates to finding cancerous tumours in the body.
Back in his lab at the Institute of Cancer Research, Leo demonstrates how his specially-developed ultrasound equipment can clear identify tumours where normal ultrasound would fail.
