Researchers are working to develop and test a blood test that can detect colorectal cancer and advanced polyps by looking for specific markers in your blood. This study is collecting blood samples from three groups of people: those with suspected advanced polyps, those newly diagnosed with colorectal cancer who are scheduled for surgery, and those undergoing routine cancer screening. The goal is to see how well this blood test can identify people at risk or with early signs of colorectal cancer.
Currently, colorectal cancer screening often relies on colonoscopy, which is invasive and uncomfortable for many people. Researchers hope this blood test will offer a simpler, less invasive way to detect colorectal cancer and advanced polyps early, when treatment is most effective.

Your participation is straightforward: you will visit the study site once and provide a blood sample (about 40 milliliters, or roughly 3 teaspoons). If you are in the screening group, this will happen around the time of your routine colonoscopy. The researchers will also collect information about your medical history and your colonoscopy results. There are no follow-up visits or ongoing treatment—this is a one-time sample collection to help develop the blood test.
