What cancers does the Galleri test screen for?

In a clinical study, Galleri detected a signal shared by over 50 types of cancer —including some fast-spreading and aggressive cancers responsible for approximately two-thirds of cancer deaths.1 Galleri is a cancer screening test, meaning it looks for cancer before symptoms appear. 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.
