MEDICAL EXPOSURE IN LUNG CANCER SCREENING BY HELICAL COMPUTED TOMOGRAPHY

Lung Cancer Screening by Helical Computed Tomography

[Computed tomography in screening for lung cancer].

Technology and target group: Approximately 2 800 new cases of cancer in the lungs and respiratory tract are diagnosed annually in Sweden. By the time it is diagnosed, the cancer has usually spread in the body, and the 5-year survival rate following diagnosis is approximately 10 percent. If cancer could be detected at an early stage, the hypothesis is that it would substantially improve the prog...

Computed tomography screening and lung cancer outcomes.

CONTEXT Current and former smokers are currently being screened for lung cancer with computed tomography (CT), although there are limited data on the effect screening has on lung cancer outcomes. Randomized controlled trials assessing CT screening are currently under way. OBJECTIVE To assess whether screening may increase the frequency of lung cancer diagnosis and lung cancer resection or may...

Computed tomography screening for lung cancer.

The development of CT technology reopened the lung cancer screening debate. Computed tomography screening for lung cancer certainly meets all the criteria required for an appropriate screening test. First and perhaps most importantly, the disease for which the screening is being performed should have a significant prevalence in the population being studied and be a significant health risk for t...

Low-dose computed tomography lung cancer screening.

Lung cancers, primarily caused by tobacco smoking, are the leading cause of cancer deaths in the United States and around the world. Screening of select high-risk patients using low-dose helical computed tomography (LD-CT) has been shown to reduce lung cancer mortality by 20% compared with chest radiography. However, because there are risks to LD-CT lung cancer screening, it should be performed...
