Blood-cell transplants slow kidney cancer
By Nathan Seppa
Physicians call renal-cell cancer a silent malignancy because it usually develops in people
without producing pain or other symptoms. If the cancer, which seldom responds to drugs, is
detected while still confined to a kidney, removing that organ can save a patient. In most
cases, however, this stealthy cancer spreads before it’s found and on average, is fatal within a

Researchers now report some success in fighting this kidney cancer by using blood from a
