For-profit Cancer Industry: The nuclear arms race in hospitals

[flashl]

There is a new nuclear arms race under way — in hospitals.

Medical centers are rushing to turn nuclear particle accelerators, formerly used only for exotic physics research, into the latest weapons against cancer.

Some experts say the push reflects the best and worst of the nation’s market-based health care system, which tends to pursue the latest, most expensive treatments — without much evidence of improved health — even as soaring costs add to the nation’s economic burden.

The machines accelerate protons to nearly the speed of light and shoot them into tumors. Scientists say proton beams are more precise than the X-rays now typically used for radiation therapy, meaning fewer side effects from stray radiation and, possibly, a higher cure rate.

But a 222-ton accelerator — and a building the size of a football field with walls up to 18-feet thick in which to house it — can cost more than $100 million. That makes a proton center, in the words of one equipment vendor, “the world’s most expensive and complex medical device.”
