Paul Davies Cancer Quotations

It will be in the convergence of evolutionary biology, developmental biology and cancer biology that the answer to cancer will lie. Nor will this confluence be a one-way street.

In the frantic search for an elusive 'cure,' few researchers stand back and ask a very basic question: why does cancer exist? What is its place in the grand story of life?

Cancer is not something confined to human beings. It's found in all multi cellular organisms where the adult cells proliferate, so it's widespread in the biosphere. It's a phenomenon that is deeply related to the history of life itself, so by studying cancer I think we can illuminate the history of life itself and vice versa.

Cancer cells come pre-programmed to execute a well-defined cascade of changes, seemingly designed to facilitate both their enhanced survival and their dissemination through the bloodstream. There is even an air of conspiracy in the way that tumours use chemical signals to create cancer-friendly niches in remote organs.

Astonishingly, in spite of decades of research, there is no agreed theory of cancer, no explanation for why, inside almost all healthy cells, there lurks a highly efficient cancer subroutine that can be activated by a variety of agents - radiation, chemicals, inflammation and infection.

Studying cancer could provide huge insights for astrobiologists into the nature of life itself.

Cancer is like another form of life. It's closely related to healthy life. A healthy body is one form of life. Cancer is in a way nature's experiment with life.

Cancer is such a ruthless adversary because it behaves as if it has its own fiendishly cunning agenda.

You've got to get away from the idea cancer is a disease to be cured. It's not a disease really. The cancer cell is your own body, your own cells, just misbehaving and going a bit wrong, and you don't have to cure cancer. You don't have to get rid of all those cells. Most people have cancer cells swirling around inside them all the time and mostly they don't do any harm, so what we want to do is prevent the cancer from gaining control. We just want to keep it in check for long enough that people die of something else.

Cancer touches every family in one way or another. As other diseases are brought under control, cancer is set to become the number one killer, and is already in epidemic proportions worldwide.

Although the elusive 'cure' may be a distant dream, understanding the true nature of cancer will enable it to be better controlled and less menacing.
