Biomarker tests may provide information about changes, or mutations, in the cells that became cancer and whether a treatment is available that targets this change.
To help you understand and share this information, you can request our free booklet that summarizes the detailed information presented here. (Published in January 2018)
For some kinds of lung cancer, biomarker testing may be performed to provide information on whether there are changes in the cancer cells that can be targeted with specific drugs. We strongly advocate that people diagnosed with advanced-stage non-small cell lung cancer speak with their doctor about comprehensive biomarker testing.
The Targeted Therapy section of this website discusses biomarker testing and explains:
- The mutations that may allow lung cancer to grow (see "What is a mutation?")
- How testing for these mutations is done, and what targeted therapy drugs are currently available (see "How is biomarker testing performed?”)
- Who should have their tumor tested, and when, since the information can influence treatment choices (see “Who should have their tumor tested and when?”)
