Brain tumors known as Glioblastoma multiform cancer (GBM) are a particularly insidious form of the disease because they just don't stay still. They travel through the brain by sliding along blood vessels and nerve passageways. This means that sometimes they move to parts of the brain where surgery is extremely difficult -- if not impossible -- or that even if the bulk of a tumor can be removed, chances are good its tendrils would still exist throughout the brain.
Scientists at Georgia Tech may have come up with a novel solution for this problem; though, it may be years before the technique can be used on humans. It involves creating artificial pathways along which cancer can travel. These pathways could route cancer to a more easily operable area, or even to a deadly drug located in a gel outside the body. … Read more
