screening had a high false-positive rate and used ionizing radiation. A false-positive result means that a positive screening result is later found to not represent lung cancer. In the NLST, false-positive results occurred in about 1 of every 4 baseline and first-year annual CT screening ...
Lung cancer screening with LDCT is a complex and controversial topic, with inherent risks and benefits. Results from the large, prospective, randomized NLST show that lung cancer screening with LDCT can decrease lung cancer-specific mortality by 20% and even decrease all-cause mortality by 7%,8 ...
