If you’re only broadly aware that ctDNA is something people are talking about, then read on.

ctDNA stories are some of the most popular stories we publish on our website. If any of you missed our liquid biopsies webinar with Gary Pestano, that’s a great place to start familiarising yourself with the basic premise and how it’s applied to diagnostics. Broadly speaking, ctDNA is single- or double-stranded DNA released by tumour cells into the blood. It can be detected in tiny amounts, and offers several advantages over traditional tissue biopsy methods. Using it as a biomarker makes for a highly sensitive and specific tool to not only detect cancer earlier, but also change how we approach tumour management.
