A Ted-Ed Animated Lecture on How Cancer Cells Behave Differently in the Body

In this incredibly informative 2012 Ted-Ed animated lecture, writer and scientist George Zaidan talks about how cells rapidly divide within the body and why a rogue cell can cause cancer. He also explains why chemotherapy works to kill cancerous cells and why baldness and nausea are very common side effects.

How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division. George Zaidan explains how rapid cell division is cancer’s “strength” – and also its weakness.
