The video discusses immunotherapy, a treatment that uses the body's immune system to target cancer cells. It explains how cancer cells can hide from the immune system and how immunotherapy helps unmask them for destruction.

Current research aims to understand the immune system's interaction with these cancers and improve immunotherapy's effectiveness.
