Cancers Might Be Newly Evolved Species

Cancerous tumors are parasitic organisms , according to a new article in the journal Cell Cycle argues that cancers are new species evolve .

Each cancer is a new species that, like other parasites, depends on its host for food but otherwise operates independently and often at the expense of its host, according to project leader, Peter Duesberg.
Duesberg, professor of molecular and cellular biology at the University of California, Berkeley, and his colleagues believe that carcinogenesis -the generation of cancer is just another form of speciation, the evolution of new species.

"Cancer is comparable to a bacterial level of complexity, but still autonomous, ie not dependent on other cells for survival, not follow orders like other cells in the body, and can grow where, when and how you like "Duesberg said in a news release from the University of Berkeley. "That's what we are all about species ... Once a cell has crossed the barrier of autonomy, which is a new species."
The key to this new theory is that he and his team denies the widely held view that tumors begin when a handful of mutated genes send a cell into uncontrolled growth. Instead, they argue that carcinogenesis is initiated by an alteration of chromosomes, leading to duplicates, deletions, breaks and other chromosome damage that alter the balance of tens of thousands of genes. The result is a cell with totally new features -., That is, a new phenotype represents a unique species
The idea is already gaining support from other experts. Mark Vincent, a medical oncologist at the Cancer Program London Regional and University of Western Ontario, said, "I think Duesberg is correct by criticizing mutation theory, which supports a drug industry billion focused on blocking these mutations. However, very, very few cancers have been cured by targeted therapy drug, and even if a drug helps a patient survive six or nine months, cancer cells often find a way around it. "
Recently I interviewed Tak Mak , one of the leading cancer researchers in the world, and frustration also expressed about the pharmaceutical industry billions of dollars that seems to employ many, and however, it results in the few effective treatments.

Duesberg and others hope that the new form, or rekindled, looking Cancer it could help understand their growth and spread, leading to better therapies or drug targets. ( "Restored" as the evolutionary biologist Julian Huxley wrote in 1956 that "Once the neoplastic process has crossed the threshold of autonomy, the resultant tumor can be logically regarded as a new biological species ...." Other researchers and Huxley proposed that cancer is more like a parasite disease.)
Because the chromosomes altered cancers recent developments are visible under a microscope, it may be possible to detect cancers earlier. And Pap tests dependent changes in the forms of the cells of the cervix as an indication of chromosomal problems that could lead to cervical cancer.
Cancer should be beatable. As Vincent points out, cancers are probably operating right on the edge of survival, maintaining genomic flexibility while retaining the ability to divide forever. Leading them to evolve more rapidly, he said, "could push them over the edge."
