CT scans can stop lung cancer sooner
A study of 53,000 current and former smokers showed that screening with low-dose CT scans cut lung cancer deaths by 20 percent over standard x-rays. Temple University Hospital already has a screening program for high-risk patients, such as smokers, or those with a family history of lung cancer. Parag Desai of the Temple Lung Center says, "We look for high-risk patients, somebody who's smoked for a long time, who has diagnosed or undiagnosed emphysema or COPD." Desai says the program has caught some early-stage growths, giving patients better odds.
