Lesson description

In this lesson, you will learn about the role of blood tests, a type of liquid biopsy, in detecting cancer. The lesson describes some common blood tests that may provide information on cancer, such as Complete Blood Count (CBC), circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA). It covers how these tests can help detect cancer, assess treatment response and monitor for recurrence. You will also gain an understanding of common blood biomarkers for different cancers and the limitations of using blood tests alone for diagnosis. The lesson highlights emerging biomarker technologies and emphasizes the importance of consulting healthcare professionals for accurate diagnosis and treatment guidance.
