Brown researchers find CT scans reduce lung cancer mortality
By Megan Hall
Providence, RI – Doctors now have a new tool in preventing lung cancer deaths. A study designed by researchers at Brown University shows computerized tomography or CT scans are twenty percent more effective than X-rays at catching the disease before it turns fatal.
CT scans offer a more complex view of tissues and bones than an X-ray.
The research collected data from more than fifty thousand people who smoked at least a pack a day. Over the course of eight years, the subjects who received CT scans were twenty percent less likely to die of lung cancer than the subjects who received X-rays.
But lead statistician and Brown Professor Constantine Gatsonis says lung cancer still remains a deadly disease. "There is some medical technology available that can help detect cancers early and it's effective in reducing mortality from lung cancer," Gatsonis say, "but it's only effective in reducing mortality, it won't eliminate mortality.
The findings were so overwhelming the National Cancer Institute ended the study early.
