A liquid biopsy, also known as fluid biopsy or fluid phase biopsy, is the sampling and analysis of non-solid biological tissue, primarily blood. [1] [2] Like traditional biopsy, this type of technique is mainly used as a diagnostic and monitoring tool for diseases such as cancer, with the added benefit of being largely non-invasive.
MRD is a form of liquid biopsy, which has other applications such as multi-cancer screening tests. [ 4 ] Molecular tests that uncover minimal residual disease are helpful for directing treatment and monitoring or preventing relapse.
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...

Ultrasonographic findings will also guide the indication to biopsy and the long term follow-up. [10] High frequency transducer (7–12 MHz) is used to scan the thyroid nodule, while taking cross-sectional and longitudinal sections during scan.
Most notably, it has led to what is now known as liquid biopsy. In short, liquid biopsy is using biomarkers and cancer cells in the blood as a means of diagnosing cancer type and stage. [24] This type of biopsy is noninvasive and allows for the routine clinical screening that is important in determining cancer relapse after initial treatment. [25]
