RecruitingDiagnostic testUnintentional Weight Loss and Cancer: A Prospective Trial of Patient-centered Weight Tracking CombinUnintentional weight loss (UWL) is commonly associated with a wide variety of diseases and there is still no valid diagnostic pathway for evaluating UWL. When detecting UWL coupled with GRAIL Galleri testing, (an investigational pan-cancer early detection test), it is thought that there is a greater positive predictive value in detecting malignancies. This study aims to test the potential synergistic effects of UWL detection and GRAIL usage to detect malignancy at an even earlier rate. UWL will be measured using weekly weight tracking.
