 Is there a way that I can tell a cancer cell is going to be sensitive to this treatment? What was discovered at MIT in Dana-Farber was that if you take live cancer cells out of a patient and we do have to have live cells and you apply an effective cancer drug to those live cells, they change their weight by a tiny amount. I mean really really minuscule very quickly. And then four or five days later the drug will actually kill the cell but in a few hours we can tell if the drug is going to kill the cell four or five days later or not. And by using that really sensitive measurement that would happen so quickly we could build a two-day turnaround cancer therapy guidance test that predicts which cancer drugs are going to work for which cancer patients.
