Lung cancer screening in Canada
ثبت نشده
چکیده
The potential value of screening for lung cancer with low-dose CT scans is currently a topic of much research and debate. This article reviews the existing trials of lung cancer screening, using chest x-ray and low-dose CT scan. Potential harms of screening, including overdiagnosis and radiation exposure, are addressed. Practical difficulties of organizing a screening program in Canada include defining the screening population, reaching that population, and establishing a relationship between screening and smoking cessation programs.
