"Grail's Multi-Cancer Blood Test Shows Promise in Large Study"

Grail, a blood testing company, presented the results of a large study at ASCO23, which showed that its commercial blood test, Galleri, could be used to diagnose patients suspected of having cancer due to symptoms such as abdominal pain, rectal bleeding, or unexplained weight loss. The test searches for the genetic fingerprints of cancer in the blood, and Grail hopes that doctors will consider it as an alternative to expensive scans or invasive biopsies.
