Circulating Tumor DNA

Circulating tumor DNA (ctDNA) refers to small fragments of genetic material released into the bloodstream by cancer cells. When tumors grow, they shed bits of their DNA, which can be detected in blood tests. By analyzing ctDNA, doctors can gain insights into the type and characteristics of a patient’s cancer, monitor treatment effectiveness, and even detect recurrences. This non-invasive technique offers a way to assess cancer without needing more invasive procedures, making it an important tool in modern oncology for personalized treatment plans and real-time monitoring of cancer progress.
