Abstract

Cheng Wei*

Cancer remains one of the leading causes of death worldwide, with early detection and continuous monitoring being pivotal in improving survival rates. Traditionally, cancer diagnosis and monitoring have relied on invasive methods such as tissue biopsies and imaging techniques, which can be uncomfortable, costly, and often impractical for routine use. In recent years, liquid biopsy has emerged as a revolutionary non-invasive alternative for cancer diagnosis, treatment monitoring, and detection of Minimal Residual Disease (MRD).
