"Liquid biopsy" sounds like science fiction, but it is simply modern slang for a multi-cancer blood test.
In clinical settings, a liquid biopsy means analyzing a standard blood sample for early signs of cancer. In the US, it is often used interchangeably with Multi-Cancer Early Detection (MCED) testing. Instead of invasive procedures, we scan the bloodstream for tumor DNA fragments to catch early signals.
