"When those of us who are now middle-aged went to high school and to college, what we learned about cancer was completely descriptive. We learned how cancer cells look compared to the way normal cells look and it was beautiful, it was elegant. We learned how cancerous organs look compared to the way normal organs look. We learned about how patients decline with cancer. But it was very frustrating at least for me, because we didn’t have any understanding or sense of why these processes were occurring. Exactly what was happening, why it was it happening, when was it happening, how was it happening, all the questions you ask of mystery. We now don’t have them all answered — if it were an easy problem it would have long since been solved. But we do have a very good sense of the kinds of changes that a cell undergoes between the time it is a normal cell and the time that it is growing completely out of control, causes a tumor that can invade, metastasize and kill its host."
