Circulating Tumor Cell Testing - Metastatic Breast Cancer Trial Talk

From the Experts

A circulating tumor cell (CTC) test is a blood test that looks for tumor cells that were shed from a tumor and are now moving (circulating) through the bloodstream. Currently, CellSearch is the only FDA-approved CTC test for metastatic breast cancer.

Researchers are still studying how to use CTC tests to better monitor and treat metastatic breast cancer. Below you will find links to articles that define CTCs, discuss how CTC tests currently help patients, and explore how CTC tests may be used soon.
