New device invented at University of Rochester and being commercialized has potential for stopping the spread of cancer by filtering the blood for renegade cancer cells:
"When someone has a primary cancer tumor, a small number of cancer cells circulates through the bloodstream. In a process called metastasis, these cells are transmitted from the primary tumor to other locations in the body, where they form secondary, cancerous growths.
"As a cancer cell flows along the implanted surface, King’s device captures it and delivers an apoptosis signal, a biochemical way of telling the cancer cell to kill itself. Within two days, that cancer cell is dead. Normal cells are left totally unharmed because the device selectively targets cancer cells."
