Researchers are evaluating the performance of two new blood-based tests designed to help detect cancer in adults aged 45 and older who show symptoms or signs that suggest cancer might be present. These tests focus on multiple cancers, including those in the gastrointestinal system, to improve early diagnosis and guide further medical evaluation. Participants will have up to 40 mL of blood collected for analysis with the investigational diagnostic tests. For those suspected of having cancer, standard diagnostic procedures will be followed to confirm the diagnosis, while participants already diagnosed with cancer must not have started treatment prior to enrollment. The results of the investigational tests will be kept confidential and will not influence clinical care decisions, ensuring unbiased evaluation. During the 18 months following enrollment, researchers will assess the accuracy and performance of these diagnostic tests by comparing their results with clinical diagnoses confirmed through standard care. Participants may undergo routine clinical evaluations, imaging, and pathology reviews as part of their care. The study team will monitor outcomes and maintain blinding to test results to ensure objective assessment throughout the study period.
