“Brain tumors are one of the most devastating consequences of cancer’s spread—hard to treat and highly deadly. Scientists have found that using a radioactive implant precisely where a tumor was removed in the brain can help patients get their cancer treated more quickly and in many cases, live longer.

A new study showed that GammaTile, a radioactive wafer the size of a postage stamp, nearly doubled survival rates and nearly eliminated tumor regrowth in people who had it placed in the spot where brain tumors were surgically removed.”
