In this episode of The Cancer SIGNAL, Nima Nabavizadeh, MD, an associate professor of radiation medicine at Oregon Health & Science University (OHSU) and the chief medical officer at the Cancer Early Detection Advanced Research Center (CEDAR) at OHSU, joins host Susanna Quinn to share the results from the groundbreaking GRAIL PATHFINDER 2 clinical trial unveiled at the European Society for Medical Oncology (ESMO 2025) Congress. As the principal investigator for the trial, which examined the safety and performance of the Galleri multi-cancer early detection test, Dr. Nabavizadeh discusses why the findings are pivotal for patients and could potentially redefine early cancer detection.

The Galleri test does not detect a signal for all cancers. Not all cancers can be detected in the blood. False positive and false negative results do occur. Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer. The Galleri test should be used in addition to healthcare provider recommended screening tests.

Based on a clinical study of people ages 50 to 79, around 1% are expected to receive a Cancer Signal Detected result. After diagnostic evaluation, around 40% of these people are expected to have a confirmed cancer diagnosis.

In this episode of The Cancer SIGNAL, Tad Carper, Senior VP of Communications for the Dallas Cowboys, shares how a multi-cancer early detection (MCED) screening unexpectedly revealed a cancer signal for head and neck cancer—despite experiencing no symptoms. The test, sponsored for the team's assistant coaches by quarterback Dak Prescott's foundation, Faith Fight Finish, was the first step toward Tad's stage two cancer diagnosis. Tad reflects on the emotional and mental impact of his diagnosis, the importance of early detection, and how the experience reshaped his values—deepening his appreciation for life, relationships, and the power of proactive health care. His story highlights the critical role of accessibility, awareness, and advocacy in cancer detection, and his commitment to "paying it forward" by helping others take early action in their own health journeys.

The overall sensitivity in study participants with head and neck cancer was 85.7% (63.2% for stage I, 82.4% stage II, 84.2% stage III, 96.0% stage IV).

Based on a clinical study of people ages 50 to 79, around 1% are expected to receive a Cancer Signal Detected result. After diagnostic evaluation, around 40% of these people are expected to have a confirmed cancer diagnosis.

At a semiannual primary care visit, Jack's doctor mentioned multi-cancer early detection (MCED) testing. Though Jack wasn't experiencing symptoms, and has no family history of cancer, he decided to take the test. Two Cancer Signal Detected results from MCED screening tests taken six months apart helped his care team determine the necessary diagnostics that confirmed an early-stage cancer diagnosis. Listen to Jack's story to learn more about the impact early cancer detection had on his life.

Dr. Patrick McGill was instrumental in introducing Community Health Network to multi-cancer early detection (MCED) testing and integrating it into routine screenings offered to patients. Dr. McGill is Executive Vice President and Chief Transformation Officer at Community Health Network, and as a practicing primary care physician he believes strongly in the importance of catching cancer as early as possible to improve outcomes for patients. In this episode he shares how MCED has made an impact at Community Health Network.

Dr. Eric Klein, Distinguished Scientist at GRAIL, provides a research update from GRAIL's 2024 findings on multi-cancer early detection (MCED) testing, presented at ASCO, ESMO, AACR and more. He explores insights from the first real-world evaluation of repeat multi-cancer early detection testing, data on how multi-cancer early detection (MCED) testing is helping cancer survivors by detecting recurrence and new cancers, and findings on using MCED to detect high grade, clinically significant prostate cancer over indolent cases. Plus, the economic and emotional impacts of cancer screening, and three insightful case studies.
