As a second part of a recent video I did that introduces the concept of a mixed response in lung cancer (or many other cancers) and how we might manage that situation, I wanted to cover the biology of what is presumably occurring.  Here's a video that covers this issue, as well as the implication that we can learn more about this by doing multiple biopsies, more than is considered as the typical standard now.

Would you want to undergo multiple biopsies of different areas of the cancer, even if it might not provide a direct benefit to you but could move forward our understanding of cancer biology for the future.
