Tiny magnets used to seek out and destroy cancer cells

"Just a few decades ago, it was the stuff of science fiction: tiny devices injected into the blood stream that can seek out and destroy cancer cells.

But now scientists believe techniques dreamt up in films such as the 1960s classic
Fantastic Voyage and its remake Inner Space, could be viable within a decade.

Researchers have developed tiny magnets that can be attached to anti-body cells or stem cells that are programmed to seek out tumours in the body.

They then piggy-back their way through the blood stream before clumping themselves around the malignant tumour.

Another magnet outside the body is then used to heat them up and destroy the cancer cells."
