Hunting for the 'dark matter' of human carcinogenesis
In the 13 December 2023 issue of Atlantic magazine, medical oncologist and Pulitzer Prize winning author Siddhartha Mukherjee employs a metaphor from physics and cosmology, the existence of poorly understood dark matter and energy to relate a puzzle in contemporary oncology – just what causes a cancer to form in the first place, a process termed carcinogenesis. Analogous to the problem cosmologists face in a shortfall in their understanding the forces governing galaxies and an expanding universe, so too do oncologists now realize how our belief that carcinogenesis was the sole product of successive gene mutations has proven inadequate to account for many of the actual circumstances preceding some cancers encountered in the clinic and studied in the lab. Dr. Mukherjee begins his story in California in the 1970s, which at the time was a hotbed of medical research into the molecular basis of cancer. Pivotal then was the discovery at the University of California at San Francisco of how a...
