Smallpox 'clue' to cancer spread
THE smallpox vaccine may hold a vital clue to the way cancer spreads around the body, scientists have found.
Researchers discovered that a protein called N-WASP determines how fast the vaccina virus – the virus used as a vaccine to eradicate smallpox – moves.
A similar mechanism may be used by cancer cells, they believe. Understanding how this works may lead to new methods of slowing down or stopping the spread of cancer.
The spread of tumour cells from one part of the body to another is the main reason why cancer can be so hard to treat.
