Melissa made annual Galleri testing part of her routine health screening. In this patient testimonial, Melissa shares why recurring annual screening with the Galleri multi-cancer early detection test became important to her, and how one blood test can help screen for a cancer signal across more than 50 types of cancers, including many that do not have recommended screening tests today. When a cancer signal is detected, Galleri is designed to predict the Cancer Signal Origin, which can help healthcare providers understand where to look next and guide follow-up diagnostic testing. Melissa’s story is a powerful reminder that early detection can start with being proactive, staying consistent, and talking with your healthcare provider about whether Galleri is right for you.

The Galleri test does not detect a signal for all cancers and 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. Based on a clinical study of people ages 50 to 79 around 1% are expected to receive a Cancer Signal Detected result, which includes a predicted Cancer Signal Origin. After diagnostic evaluation, around 62% of these people are expected to have a confirmed cancer diagnosis. The overall sensitivity in study participants with liver/bile duct cancer was 93.5% (100% for stage I, 70.0% stage II, 100% stage III, 100% stage IV). Rx only.
