Cancer is the oldest in the world

UK experts have found the cancer germ continues to spread today since "rooted" in a dog 11,000 years ago.

Researchers at the Sanger Institute of the Wellcome Trust near Cambridge (UK) decoded the DNA of this cancer line, which did not die when the host died of live cancer cells that could be transmitted to other subjects in mating process.

The cancer genome of 11,000 years old carries about 2 million mutations, many times more than the number of 1,000 to 5,000 mutations in most cases of cancer appearing on the human body.

'The genome of this impressive, long-lived cancer has shown that in the right conditions, cancer can survive for more than 10,000 years despite an increase in millions of mutations' , according to Healthday quoted expert Elizabeth Murchison. .

This type of cancer that is transmitted through the genital tract still exists in the body of the first dog that is sick, which according to researchers looks like Alaskan Malamute or Husky.

'We still don't know why the individual has produced a contagious cancer line , ' said Murchison.

Infectious cancer is extremely rare in nature, because it is unusual for cancer cells to leave the host's body and infect others.
