Cancers Are Newly Evolved Parasitic Species, Biologist Argues

Cancer patients may feel like they have alien creatures or parasites growing inside their bodies, robbing them of health and vigor. According to one cell biologist, that’s exactly right. The formation of cancers is really the evolution of a new parasitic species.

Just as parasites do, cancer depends on its host for sustenance, which is why treatments that choke off tumors can be so effective. Thanks to this parasite-host relationship, cancer can grow however it wants, wherever it wants. Cancerous cells do not depend on other cells for survival, and they develop chromosome patterns that are distinct from their human hosts, according to Peter Duesberg, a molecular and cell biology professor at the University of California-Berkeley. As such, they’re novel species.

He argues that the prevailing theories of carcinogenesis, or cancer formation, are wrong. Rather than springing from a few genetic mutations that spur cells to grow at an uncontrolled pace, cancerous tumors grow from a disruption of entire chromosomes, he says. Chromosomes contain many genes, so mis-copies, breaks and omissions lead to tens of thousands of genetic changes. The result is a cell with completely new traits: A new phenotype.

Cancer as evolution in action, which represents a fundamental re-thinking of the disease, has been proposed before — evolutionary biologist Julian S. Huxley first described autonomously growing tumors as a new species back in 1956, according to a Cal news release. But the prevailing view has long been that cancer is the result of genetic mutations.

In our latest infographic, we take a look at the numbers behind the healthcare costs associated with being a woman:

The Institute of Medicine has named eight preventive services that women should get for free under the new health care law. Exactly how much money are we talking about? GOOD took stock of the money spent by a “typical” American woman whose sexual health and life choices correlated with the national averages. Turns out being a woman is pretty pricey.

Not So Far Out: In the past decade, research into the effects of psychedelic drugs on consciousness has become a growing field of study in American academia. Psychologists at UCLA, Johns Hopkins Medical School, and NYU, among other places, have published research showing that psychedelics can promote happiness in ordinary people, as well as alleviate depression and anxiety among the terminally ill.
