Blood Test spots Cancer a year early using ctDNA analysis:
Researchers have taken an important step toward better lung cancer treatment by using blood tests to track genetic changes in tumors as they progress from their very earliest stages.
With experimental tests that detect bits of DNA that tumors shed into the blood, they were able to detect some recurrences of cancer up to a year before imaging scans could, giving a chance to try new therapy sooner.
It’s the latest development for tests called liquid biopsies, which analyze cancer using blood rather than tissue samples. Some doctors use these tests now to guide care for patients with advanced cancers, mostly in research settings. The new work is the first time tests like this have been used to monitor the evolution of lung tumors at an early stage, when there’s a much better chance of cure.
I really like this idea floating around in my head of mythological creatures getting pissed when aliens invade and try to enslave humanity in the same way that an older sibling is allowed to pick on their younger siblings, but the second somebody else picks on their younger sibling they will fight to defend them.
