Spanwise Verdict
The Galleri test represents a paradigm shift in cancer screening. Standard screening only covers 5 cancer types (breast, cervical, colon, lung, prostate). Galleri screens for 50+ types through a single blood draw, including deadly cancers like pancreatic, ovarian, and liver that are typically caught too late. Sensitivity is highest for advanced cancers and lower for early-stage disease — it complements, rather than replaces, standard screening.
