Final answer:

Liquid biopsy, or cell-free/circulating tumor DNA testing, offers high sensitivity and specificity, making it a valuable tool for cancer detection and monitoring.


Explanation:

Liquid biopsy, or cell-free/circulating tumor DNA testing, has been shown to have very high sensitivity and specificity. This type of testing involves analyzing fragments of DNA released by tumor cells into bodily fluids like blood, providing a non-invasive method for detecting cancer mutations.

By utilizing PCR technology, liquid biopsy can detect cancer-related mutations early on, allowing for personalized cancer treatments and improved diagnostic capabilities.

High sensitivity in liquid biopsy means a low false negative rate, while high specificity leads to a low false positive rate, making it a valuable tool in cancer detection and monitoring.
