In a study published online this week in theProceedings of the National Academy of Sciences, a US team of biomedical engineers demonstrates a way to stop migrating cancer cells dead in their tracks as they travel through the bloodstream to set up new tumors.
Metastasis is where cancer cells from a firsttumor detach and spread to other parts of the body.
Surgery and radiation are usually quite effective for treating primary tumors, but once cancer cells start migrating the chances of successful treatment worsen considerably, partly because they are difficult to track down. The vast majority of deaths from cancer are due to metastasis.
Now, a new study suggests it is possible not only to locate these migrating cancer cells, but to annihilate them before they have a chance to set up secondary tumors.
