Cancer patients may palpate like they have foreign fauna growing inside their eubstance , robbing them of health and vigor . accord to one cadre biologist , they ’re on the nose ripe . The formation of cancers is really theevolution of a new bloodsucking species .
Just as leech do , cancer look on its host for sustenance , which is why treatments thatchoke off tumorscan be so efficient . Thanks to this sponger - host relationship , Crab can originate however it wants , wherever it need . Cancerous cadre do not depend on other cells for survival , and they develop chromosome patterns that are distinct from their human emcee , according toPeter Duesberg , a molecular and cell biology professor at the University of California - Berkeley . As such , they ’re novel coinage .
He argues that the prevailing theories of carcinogenesis , or cancer formation , are wrong . Rather than springing from a few genetic mutation that spur cells to grow at an uncontrolled pace , cancerous tumor grow from a gap of entire chromosomes , he says . Chromosomes contain many genes , so Secret Intelligence Service - copies , breaks and omission lead to tens of thousands of genetic changes . The result is a cell with completely unexampled trait : 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 discover autonomously growing tumors as a new species back in 1956 , according to aCal news waiver . But the triumph position has long been that cancer is the result of transmissible mutant .
Oncologists and pharmaceutic researchers are studying ways to find and block those mutations , aiming to turn off the transposition that sparkle carcinogenesis . But gene therapy has largelyfailed to delivermany meaningful results .
Duesberg argues , controversially , that it ’s misguided . Chromosomal mutation , shout aneuploidy , is the cause instead , and it destabilise chromosomal pattern . Some of the disrupted chromosomes are able to divide , seeding malignant neoplastic disease . The termination is a new chromosomal pattern that is clear-cut from our own . The Cal news show office explains this in much enceinte item .
Duesberg said he hopes this hypothesis will spark new types of cancer diagnosis and treatment . Chromosomal tests could potentially beak out aneuploidy very early , before the damaged chromosomes have had a chance to carve up , for representative . And new treatment could direct the chromosomal disruptions , rather than knocking out or switching off genes .
