Researchers are looking for early warning signs—called biomarkers—that might help predict who will develop lung cancer, head and neck cancer, or esophageal cancer. By collecting and studying tissue samples from people with these cancers or precancerous changes in their airways, the study aims to understand what happens in the cells before cancer develops. This knowledge could eventually help doctors catch cancer much earlier, when it's easier to treat.
Right now, doctors have limited tools to predict which patients with precancerous changes in their airways will actually develop cancer. By identifying specific biological markers that appear early in this process, researchers hope to create better screening methods and catch these cancers at earlier, more treatable stages.

If you qualify, you'll undergo a bronchoscopy—a procedure where a thin tube with a camera is gently passed into your lungs so doctors can collect small tissue samples, fluid, and cell brushings. You may also provide a sputum (coughed-up fluid) sample. All samples are sent to a lab where researchers study them for early cancer warning signs. Unused samples are stored in a tissue bank for future research. The entire procedure typically takes place during a single visit, though some participants may need follow-up monitoring bronchoscopies.
