The Blood Test That Could Change How We Detect Cancer: Circulating Tumor Cells

For decades, cancer detection has relied on imaging tests and tissue biopsies. While powerful, those tools can be invasive and don’t always show how cancer is changing in real time. Scientists are now focusing on something called circulating tumor cells, or CTCs — these are tumor cancer cells floating in the bloodstream and the ability to detect these may completely change how we diagnose and monitor cancer. #cancer #science
