Scientists Discover How Cancer Spreads

Scientists have discovered how cancer spreads.

LONDON - Scientists have discovered how cancer spreads from a primary site to other places in the body in a finding that could open doors for new ways of treating and preventing advanced disease.

Instead of a cell just breaking off from a tumor and traveling through the bloodstream to another organ where it forms a secondary tumour, or metastasis, researchers in the United States have shown that the cancer sends out envoys to prepare the new site.

Intercepting those envoys, or blocking their action with drugs, might help to prevent the spread of cancer or to treat it in patients in which it has already occurred.

"We are basically looking at all the earlier steps that are involved in metastasis that we weren't previously aware of. It is complex but we are opening the door to all these things that occur before the tumor cell implants itself," said Professor David Lyden, of Cornell University in New York.

"It is a map to where the metastasis will occur," he added in an interview.

What can I add?

It says a lot about the future of cancer, I think. Namely that there is none. That's right. Cancer has no future.

Science is going to kick cancer's butt, plain and simple.
