What is Stage 3 Lung Cancer?
What Is   stage 3 LUNG CANCER?
As you may know, there are 2 forms of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Most people with lung cancer (about 80%-85%) are diagnosed with NSCLC.
When lung cancer is “stage 3,” that means cancer has been found in the lungs and lymph nodes in the middle of the chest.
  • You may hear your treatment team call your cancer “locally advanced NSCLC”
  • If you’re researching and reading about it online, you may see it spelled out as “stage III”
  • Your treatment team will determine if your stage 3 lung cancer is “resectable,” which means it can be removed by surgery. If it cannot be removed by surgery, doctors call it “unresectable”
Types of   Stage 3 lung cancer
Stage 3 lung cancer is divided into 3 substages: 3A, 3B, and 3C. The substage is based on how big the cancer is, if it has spread to other parts of the body, and where it has spread. Below, you will learn more about the differences of each stage 3 substage.
