Radioactive atoms blast cancer from inside

NEW YORK - Scientists say they've discovered a method using nuclear waste to
attack cancer cells without harming healthy tissue.
They've attached unstable radioactive atoms to antibodies that are attracted
to and penetrate cancer cells.
Once inside, the atoms begin to decay, releasing radiation that kills the
cancer cell, but only damages a few of the surrounding cells.
Details of research done at the Memorial Sloan-Kettering Cancer Center in
New York were released in Friday's edition of Science.
Conventional radiation treatment can cause extensive damage to healthy
tissue surrounding malignant cells because of the difficulty in aiming it
exclusively at the cancerous areas.
Researchers found that tumours in mice shrank when the rodents were injected
with the radioactive combination.
David Scheinberg, leader of the Sloan-Kettering team, said he hopes to start
human trials within the next few months.
