Finding cancer cells in blood: Chip-based method for the rapid, sensitive isolation of rare cells in blood
(PhysOrg.com) -- Even in the early stages of cancer, individual cancer cells can be found in the blood. Certain subsets of these circulating tumor cells can cause metastasis. In cases of breast cancer, it ...
