I had learned that science is a rewarding, active process of discovery, not the passive absorption of what others had discovered.

Anyone graduating from medical school in 1966 had first to fulfill military service before launching a career. Fiercely opposed to the Vietnam War, I sought to avoid it through an assignment to the Public Health Service.

In general, all cancers have been traditionally characterized by the way they appear under the microscope and the organs in which they arise.

I keep encouraging the pharmaceutical companies to put more money into R&D.

All basic scientists who look to the NCI for funding should know that I will tolerate no retreat on the study of model systems and the pursuit of fundamental biological principles.

I begin with the premise that behavior is an incredibly important element in medicine. Peoples habits, their willingness to quit smoking, their willingness to take steps to avoid transmission of HIV, are all behavioral questions.

A cancer is not simply a lung cancer. It doesn't simply have a certain kind of appearance under the microscope or a certain behavior, but it also has a set of changes in the genes or in the molecules that modify gene behavior that allows us to categorize cancers in ways that is very useful in thinking about new ways to control cancer by prevention and treatment.
