Read our Colorectal Cancer research guide →Researchers are looking for new biological markers — substances in your blood, urine, stool, and other body fluids — that could help doctors detect gastrointestinal cancers like colon, stomach, and pancreatic cancer much earlier than they can today. This study collects small tissue and fluid samples from people already having colonoscopy, endoscopy, or surgery for medical reasons. By studying these samples, researchers hope to develop better screening tests that could catch cancer before symptoms appear.
Current cancer screening methods work well but could be improved. Doctors want to find new biological markers that appear in body fluids when cancer is developing, so they can create simpler, earlier detection tests — possibly through a blood or stool test rather than requiring more invasive procedures.

You likely don't qualify if…
If you qualify, you will undergo your already-scheduled procedure (colonoscopy, endoscopy, or surgery) — nothing extra is added. During or after that procedure, the research team will collect small samples of tissue and body fluids like blood, urine, and stool. They will also collect basic information about your health history and family history from your medical records. After that, you will be checked on once a year for up to 5 years to see how you are doing and whether the markers collected predict your health outcomes.
