Liquid biopsy is a revolutionary diagnostic technique that allows for the detection of disease—primarily cancer—through the analysis of biological fluids, most commonly blood. The premise is based on the fact that tumors shed small fragments of DNA (ctDNA), RNA, and even whole cells into the bloodstream. By capturing and sequencing these fragments, clinicians can gain a "molecular snapshot" of a patient’s cancer without the need for an invasive tissue biopsy.
