Photons are CRAZY. Light acts as both a wave and a particle, AND moves way quicker than most super
computers could ever reasonably comprehend. Molecular evolution tends to happen on a similar time scale, so I find Light to be a high canidate for
both promoting and restricting cancer growth.

One of the biggest challenges in scientists' quest to develop new and better treatments for cancer is gaining a better understanding of how and why cancer spreads. Recent breakthroughs have uncovered how different cellular proteins are turned 'on' or 'off' at the molecular level, but much remains to be understood about how protein signaling influences cell behavior.
A new technique developed by Klaus Hahn, Ph.D. and his colleagues uses light to manipulate the activity of a protein at precise times and places within a living cell, providing a new tool for scientists who study the fundamentals of protein function.
In a paper published today in the journal Nature, Hahn, who is the Thurman Professor of Pharmacology at the University of North Carolina at Chapel Hill and a member of UNC Lineberger Comprehensive Cancer Center, described the technique, which uses light to control protein behavior in cells and animals simply by shining light on the cells where they want the protein to be active.
"The technology has exciting applications in basic research – in many cases the same protein can be either cancer-producing or beneficial, depending on where in a cell it is activated. Now researchers can control where that happens and study this heretofore inaccessible level of cellular control," said Hahn.
