Cancer, killing millions of people every year, originated at the same time. time as life on Earth, and therefore completely destroy it is not never succeed, scientists warn.
Despite the billions of dollars invested in countless science projects around the world, new research came to the conclusion that the disease cannot be defeated. Discovery means that with over time, cancer will be harder to cure or treat, because that he is a highly developed structure. This, in turn, suggests that the ability to develop cancer is determined intrinsic properties of cells that formed during million years.
But still, researchers from Kiel University in Germany and Catholic University of Croatia is urged not to lose heart, since understanding the nature of the enemy will give scientists additional chances in the fight against him.
Evolutionary biologists have discovered the first evidence natural tumors in two species of hydra – simple freshwater animals. They say the existence of this disease in tiny coral like polyps, organisms that first appeared hundreds of millions of years ago, suggests that cancer is an integral part of our evolution.
Professor Thomas Bosch, Team Leader said: “Cancer is as old as multicellular life on Earth and, probably never be completely destroyed. ”
In search of the origin of the cancer gene – the causes of all tumors – team stumbled on hydra tumors, said scientist Tomislav Domaset Loso.
“Even before the discovery was made, we assumed that the first multicellular organisms already had a gene that could cause cancer in people, he said. – But we tried to find evidence that prehistoric animals actually suffered from tumors. ”
Now the team believes that they have achieved impressive success on ways to understand the primary sources of cancer. Another discovery made as part of the same study, suggests that the invasive nature of the disease also acquired millions of years ago. If tumor cells are introduced into a healthy body, they can provoke tumor growth, scientists have discovered.
Note that only in the USA in 2012, the fight against cancer was more than $ 500 billion spent. Worldwide research allowed to improve the prevention of the disease, methods for its diagnosis and treatment. But every second person suffering from cancer is still dies due to illness, notes Mail Online.
