Are cancers newly evolved species?
By Robert Sanders
Cancerous tumors are parasitic organisms, he said. Each one is a new species that, like most parasites, depends on its host for food, but otherwise operates independently and often to the detriment of its host.

“Cancer is comparable to a bacterial level of complexity, but still autonomous, that is, it doesn’t depend on other cells for survival; it doesn’t follow orders like other cells in the body, and it can grow where, when and how it likes,” said Duesberg. “That’s what species are all about.”
