Finding out you have lung cancer can feel overwhelming, but understanding your specific diagnosis is the first and most important step in taking control of your health. This section will guide you through the basics of Stage I non-small cell lung cancer (NSCLC). You will learn about the precise tests used to confirm your diagnosis, how your medical team evaluates your lung health, and why analyzing your tumor’s specific traits through biomarker testing is crucial for planning your next steps.
When lung cancer is classified as Stage I, it means the cancer is in its earliest stages. In this section, we will break down what Stage I means, how doctors define the size and location of the tumor, and why catching the disease at this stage offers the greatest variety of highly effective treatment options.

No two lung cancers are exactly alike. Biomarker and molecular testing look at the genetic makeup of your specific tumor to find out what is driving its growth. In these videos, healthcare providers explore how these tests are performed and how knowing your biomarker status helps your team customize your care right from the start.
