Lung Cancer Detection
February 21, 2011
Nano-scale disturbances in cheek cells indicate the presence of lung cancer. Regular microscopy looking at chromatin, the genetic material inside a cell's nucleus, will not reveal significant dissimilarities between the cheek cells of a healthy person and those of a lung cancer patient. However, a new technique called partial wave spectroscopic microscopy (PWS) zeroes in on smaller-than-microscopic disturbances at the nano-level, which are harbingers of trouble.
