CTC (Circulating tumor cell)
CTC (circulating tumor cell) medical devices primarily utilize microfluidics, magnetic bead sorting, or filtration membrane technology to capture cancer cells in the blood. They are used for early screening, auxiliary diagnosis, prognostic assessment, monitoring treatment effectiveness, and providing a basis for personalized medication. Their applications cover breast cancer, lung cancer, colorectal cancer, etc., and they are a key technology for achieving precision cancer medicine, potentially replacing invasive biopsies.
