Understanding Cancer Stages: A Simple Explanation of the TNM System Millions of people worldwide receive a cancer diagnosis each year. Understanding the stages of cancer is crucial for patients and their families. This TED-Ed animation provides a clear and concise explanation of the TNM system used for cancer staging.

The video emphasizes that while cancer remains a serious disease, there is hope, thanks to ongoing advancements in diagnosis and treatment.
