Nanolaser Device Detects Cancer in Single Cells

I'm not sure if this will make that much of a difference. I wonder how many single cancer cells actually go on to develop into a tumor. I'm not sure if detecting every single cell that is cancerous is wirth it at this point, perhaps when we have cheap nanobots in the blood that can easily make use of this to eliminate the offending cell this will help.

Using an ultrafast, nanoscale semiconductor laser, investigators at Sandia National Laboratories in New Mexico, have discovered a way of rapidly distinguishing between malignant and normal cells. Moreover, this new technique has the potential of detecting cancer at a very early stage, a development that could change profoundly the way cancer is diagnosed and treated.
