CT Lung Screen - Low Dose CT Screening
For five years, the National Cancer Institute's National Lung Screening Trial followed more than 53,000 current and former heavy smokers between the ages of 55 and 74 who smoked at least a pack a day for 30 years or more. They were given either a spiral CT or a chest X-ray once a year for three years starting in August 2002.
The NCI announced the preliminary results in November 2010: That spiral CT scans caught malignant tumors and nodules earlier, reducing the risk of dying from lung cancer by 20 percent in middle age and elderly smokers.
Low Dose CT Screening (Computed Tomography or CAT scan) for the Chest
Low dose CT screening is a non-invasive safe test intended to replace or supplement routine chest x-rays performed in patients without symptoms or known lung disease. A recent clinical trial found that routine x-ray's where unable to detect lung cancer until they were at an advanced stage.
Low dose CT is designed to minimize the radiation exposure in asymptomatic patients while rapidly screening the lungs, allowing for the detection of pulmonary nodules. The detection of these pulmonary nodules found in the early stages could prove to be more curable.
Determine preliminary lung disease in people at risk of developing cancer who have smoked (1) pack of cigarettes per day for 10 years or (2) packs of cigarettes per day for 5 years.
