Microfluidics device captures circulating cancer cell clusters

About 90% of cancer deaths are due to metastases, when tumors spread to other vital organs, and a research group recently realized that it's not individual cells but rather distinct clusters of cancer cells that circulate and metastasize to other organs. As the group reports, they set out to gain a better understanding of these circulating cancer cell clusters. The group's microfluidic device brings a new therapeutic strategy to the fight.
