🩸 Liquid Biopsy: A New Window into Health
A liquid biopsy is a simple, non-invasive blood test that's transforming how we understand and monitor health, particularly concerning conditions like cancer.
What It Does
Instead of taking a tissue sample (like a traditional biopsy), this test analyzes tiny bits of material released from cells—such as DNA, RNA, or whole cells—that circulate freely in the blood. These fragments, often called circulating tumor DNA (ctDNA) when related to cancer, carry the same genetic information as the original cells.
Key Advantages
Minimally Invasive: It only requires a standard blood draw, making it much easier and safer for the patient than surgery.
