The Emperor of All Maladies: A Biography of Cancer

by Siddhartha Mukherjee

The discovery of HBV was an embarrassment to the NCI. The institute’s highly targeted and heavily funded Special Virus Cancer Program, having inoculated thousands of monkeys with human cancer extracts, had yet to find a single cancer-associated virus. Yet a genetic anthropologist exploring aboriginal antigens had found a highly prevalent virus associated with a highly prevalent human cancer. Blumberg was acutely aware of the NCI’s embarrassment, and of the serendipity in his work. His departure from the NIH in 1964, although cordial, had been driven by precisely such conflicts; his interdisciplinary curiosity had chafed against the “discipline-determined rigidity of the constituent institutes,” among which the NCI, with its goal-directed cancer virus hunt, was the worst culprit. Worse still for the strongest enthusiasts of the cancer virus theory, it appeared as if Blumberg’s virus itself was not the proximal cause of the cancer. The inflammation induced by the virus in liver cells, and the associated cycle of death and repair, appeared to be responsible for the cancer—a blow to the notion that viruses directly cause cancer.*
