Testing company's glitch causes false cancer scare for hundreds.

Test company Grail has admitted that a software glitch related to their telemedicine vendor, PWNHealth, caused them to send letters to about 400 patients saying they might have cancer when they do not. The glitch affected customers who had ordered their "Galleri" test. No patient health information was disclosed or breached due to the issue, and no patient harm has been reported. Grail immediately began outreach to all affected individuals and confirmed successful contact with each one.
