More lives could be saved by early detection of cancer than by any form of treatment at advanced stages. Circulating tumor cells (CTCs), which are viable cells derived from tumors, are hypothesized to represent the origin of metastatic disease.
Nanotechnology can be used to develop devices that indicate when those markers appear in the body and that deliver agents to reverse premalignant changes or to kill those cells that have the potential to become malignant. #task1Nanotechnology to fight and cure cancer
