Hold your breath: Lung cancer screens?Lung cancer lung cancer, cancer that originates in the tissues of the lungs. Lung cancer is the leading cause of cancer death in the United States in both men and women. Like other cancers, lung cancer occurs after repeated insults to the genetic material of the cell. is one of the most common and most deadly cancers. Only about 12 percent of lung cancers are cured, primarily because few lung cancers are caught before they spread. Studies have suggested that X-ray screening for lung cancer is ineffective. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the July 10 LANCET, low-dose computed tomography Computed tomography (CT scan) X rays are aimed at slices of the body (by rotating equipment) and results are assembled with a computer to give a three-dimensional picture of a structure. (CT) that allows doctors to completely scan the lung during a single breath may change that picture. Among 1,000 men and women who had smoked at least a pack of cigarettes a day for 10 years, CT scans detected cancer in 27 patients; X rays found cancer in just 7 of these people. CT also detected substantially smaller malignant tumors than those found by chest X rays. "Detecting more cancers in earlier stages changes survival prospects from dismal to very positive," says Claudia I. Henschke of New York New York, state, United States New York, Middle Atlantic state of the United States. It is bordered by Vermont, Massachusetts, Connecticut, and the Atlantic Ocean (E), New Jersey and Pennsylvania (S), Lakes Erie and Ontario and the Canadian province of Presbyterian Hospital.
