After years of research and billions of dollars expended annu eachy crabmeat clay to be a specter , arbitrarily afflicting people without evident design . In Freedman s article (2006 , he states that scientists cede produced hundreds of drugs that can cure cancer in mice , but non in humanness The research that produced the drugs tested on these mice is found on the theory that cancer is caused by faulty oncogenes , a theory popularized in the latter part of the `80s which still dominates the deliver . Specifically , the oncogenes-theory posits that cancer materializes when a number of genes in virtuoso cell are faulty resulting from a combination of transmitted traits and random mutations Some of the medicines produced deem managed to shrink tumors , while somewhat have g wiz as far as to delicacy particular types of cancer . Generally however , of these experimental medicines have proven to be a hundred percent lucky in treating cancer , let alone present itself as a promising cureThe main theme of the article centers on a theory that cancer results from cellular inst efficacy - a research pioneered by one Theodor Boveri in 1914 . Based on his studies of tumor cells under a microscope , he proposed that a cancerous tumor develops from a single cell in which an unintended scrambling of the stuff of chromosomes occurs , which in turn misdirects the cell to divide uncontrollably . This theory was enhanced later on by Lawrence Loeb , who theorized that the ruff explanation for cancer was that it emerges whenever something happens to a cell that renders it inheritableally inconstant or that keeps it from performing an accurate job of copying its genes .

Loeb s offer is that once this genetic instability happens on a blown-up scale , the chances of these unstable genes hitting a cancerous genetic sequence become greaterThis random shuffling of chromosomes and genes are note by some top researchers as a potency trigger for cancerous growth , as well as the means by which a tumor can besiege surrounding healthy tissue . The ineffectual treatment of humans through drugs developed in the laboratories seems , then , to stem from the detail that these drugs were tested on mice with genetically engineered tumors . These genetically engineered tumors are a far cry from the instability of naturally occurring cancer cellsResearchers that counseling this alternative theory point out that since genetic instability seems to be a common characteristic of almost all tumor cells , a technique to curb or bear away such instability could very well lead to a treatment , or even a cure , for approximately all types of cancer . Currently , Bert Volgstein has spearheaded research on one such technique involving master genes , or genes which may destabilise other genes by interfering with a cell s ability to make accurate copies of its chromosomes when randomly mutated . Another , more bag technique is being developed , based on the supposition that through a drug that increases cellular instability , cancer cells would be pushed into a chaotic gene replication assist that would result in too many genetic errors , which...If you pauperization to get a full essay, order it on our website: Ordercustompaper.com
