This type of attitude is typical, where one likes to dismiss new ideas and keep status quo instead of coming up with new ideas or innovations.
The point is that there is an opportunity for the Steve Jobs of health care to come up with a way, a new innovative novel way, for classification of tumors to be improved without needing biopsy. Once we have that, then we can take tests to our heart's content. Right now, the attitude of "we shouldn't have people take tests and detect cancer early because our current method of determining if they are cancerous would make it too hard" isn't acceptable.
