What do I need to know about my diagnosis?

Facing Stage IV lung cancer diagnosis can be incredibly daunting, but modern medicine has changed how advanced lung cancer is managed. Treatment focuses on treating cancer throughout the body and protecting your quality of life. This section will help you understand what a Stage IV diagnosis means, the necessary tests used to accurately map your condition, and why biomarker testing is a critical tool for identifying the exact treatments that will work best against your specific tumor cells.

What is Stage IV NSCLC?

A Stage IV diagnosis means that lung cancer has spread from its original location to the other lung, the fluid around the lungs, or to distant organs like the bones or brain. In this video, we break down how advanced lung cancer is classified.
