Cancer Spread Mystery Solved

IN a number of cancer cases, an "explosion" in single cell was able to cause much damage DNA. That is why a person can suffer from cancer quickly, but when the results of x-ray examination earlier, were not found anything suspicious.

Cancer is one of the most feared disease human beings on this earth. This deadly disease is the second leading cause of adult mortality in the western hemisphere, and is one of the major causes of child deaths from the disease between the ages of 1 to 14 years.

UN World Health Organization (WHO) declared that a diagnosis of cancer worldwide is expected to find 12 million people this year. Meanwhile, cancer deaths globally will reach seven million people.

Recently, the mystery of cancer spread so quickly, which in essence could be due to several factors, have been solved by scientists from the UK. In some cases, the "explosion" of apocalyptic in a single cell can cause some damage to the DNA as the blueprint for life.

The findings of the Wellcome Trust Sanger Institute near Cambridge, contrary to the old theory that cancer is a consequence of hundreds or even thousands of gene mutations that develop when a person's life. This shows that no matter how much effort a person to a healthy, destiny is ready to fight it.

This conclusion helps explain why some people diagnosed with cancer just months after he was run x-ray examination or other tests that did not find any signs of disease. The discovery was made from a number of studies that had lasted about a genetic weakness to 750 types of tumors.

Most cases of cancer, damage seen in the chromosomes which are equipped with the conventional picture of cancer that crept up over the years. H owever, at least, as reported in the journal Cell , one of the 40 cases were not in accordance with the standard pattern of faster growing alias. The process seems to have done such damage in just one night.

"These results are surprising kami.Itu meaning only within a single cell, in one step, one or more chromosomes explode, really into hundreds of fragments , "said researcher, Dr Peter Campbell, as reported by the Daily Mail page.
/> If the cell is later repairs, stitches the fragments back to join in the pattern of" shattered " , damage to the genome, or DNA hide, until ripe for rapid development of cancer. "The cell says 'enough', then gave up, but behind it is trying to reconnect the pieces of the chromosome as a valuable part of the porcelain," said Campbell.

"They are trying to reconstruct something that really can not be changed and the damage done to genes that could be a faster path toward cancer, "he continue d.

This phenomenon is particularly common in patients with bone cancer. Different pattern of damage was seen in one of four cases. However, it is thought to be the cause in more than one in 40 cases of the disease.

"Many cancers will take years, decades, to develop, but we also know that some cancer patients appears to be much more quickly affected than that, "Campbell said.

" We have examples of people who have the results of a mammogram or x-ray is completely normal, and within the next few months they actually had cancer and a nasty aggressive single symptom, could even accelerate the development of the disease, "he said.

Researchers are not sure what triggers the occurrence of severe cell damage due to" cancer instant ", but likely due to x-ray examination and sunburn.

" If we can understand the roots, we can learn how to prevent cancer, "said Campbell.

This study is p art of a major project to map the genetic flaws in dozens of different types of cancer. In the future, every patient could have a "chart mutation" itself, mapping the genetic flaws that became the background of their disease and showed the best medicine to treat it.

Earlier, U.S. reports National Cancer Institute who was part of USCenters for Disease Control and Prevention, The American Cancer Society and The North American Association of Central Cancer Registries, said the rate of death and diagnosis of all cancers overall declined significantly in recent years.

apply all the results of this study for both men and women, and for racial and ethnic populations of the largest in the United States. Mentioned in the report, a new diagnosis for all types of cancer declined an average of almost 1 percent per year from 1999 to 2006.
