[5] A subsequent large-scale NHS England trial has been described by experts as overhyped and unethical. Grail is facing discontent and legal action from investors who suspect that its cancer testing claims misled them.
In 2018 data from Grail's first clinical trial for the Galleri test, the Circulating Cell-free Genome Atlas Study, [5] the test detected 87% of late-stage cancers and 38% of early-stage cancers. [6] The test does not diagnose cancer; [7] rather, it detects possible signs of cancer in order to help direct follow-up diagnostic testing. [8]

Cervical cancer screening, such as the Papanicolaou test ("pap smear"), or examination of the cervix after applying acetic acid, can detect both early cancer and abnormal cells that may develop into cancer. [1] Screening allows for early treatment which results in better outcomes. [1]
