Are there new ways to detect lung cancer before it starts to spread?
One screening method that shows promise detecting lung cancer before it has spread is spiral computerized tomography or spiral CT. Spiral CT can scan the lungs from the neck to the diaphragm in less than 20 seconds, or a single breath-hold. Preliminary studies show that it may help doctors find small tumors, but questions remain about the technology’s risk and benefits as a screening tool.
