GONZALEZ, Jessica  and  DE-TORRES, Juan P.. Screening of lung cancer with low radiation dose computed axial tomography. Rev. Urug. Med. Int. [online]. 2017, vol.2, n.1, pp.4-12. ISSN 2393-6797.

Lung cancer (PC) is the cause of death due to more frequent malignant disease. At the time of diagnosis, only 15% of patients with lung cancer remain alive after 5 years because this is usually done in advanced stages. CP Screening with Computed Low-dose Axial Tomography (BDT) has been proposed as a strategy to reduce mortality through early detection and early treatment. The relationship between smoking and CP is well known, with 90% of these cancers attributed to active or passive exposure to cigarette smoke. Chronic obstructive pulmonary disease (COPD) is the most important but underrecognized risk factor (RF). Recently, the use of BDT has allowed lung emphysema to be identified as another major FR. The association between these two diseases (COPD and emphysema) increases the risk of developing COP, which makes smokers with these pathologies an ideal target for screening programs. However, the balance between benefit and damage caused by screening has generated intense debate, so the challenge lies in improving the criteria for inclusion of screening programs, minimizing the number of false positives and over-diagnosis.

This review aims to highlight the most important points about lung cancer screening and make some recommendations for its implementation.
