Harold Varmus: Well the simplistic way to think about that is and I'm not sure this is the way it will be worked out, is to be able to take just a few cells from those early lesions and examine them genetically or for other kinds of marks on the DNA that would predict whether or not this is some - this is a lesion which might or an early stage growth that might never be able to progress, but it is also possible that every early tumor of that kind has some probability of expanding and invading and growing to become a medical problem, so getting that right will obviously be crucial because it's very difficult to say when you've diagnosed something that is an early stage tumor that it won't progress.
