Background:
Lung cancer is the predominant cause of cancer-related mortality globally. Computed tomography (CT) scanning is employed to enhance the early diagnosis of lung cancer by screening for risk factors. This study aimed to examine the impact of CT scanning on the incidence of lung cancer detection in a group with unidentified risk factors for the disease.
Methods:
Data from two patient cohorts were analyzed: the "study group," comprising individuals with a CT-detected pulmonary nodule of ≥ 8 mm and unknown lung cancer risk factors, and the "control group," consisting of individuals with a pulmonary nodule of ≥ 8 mm identified by CT scan due to known lung cancer risk factors.
Results:
No significant difference was seen between the groups regarding malignancy frequency (p=0.155) and early-stage occurrence (p=0.842).
Conclusions:
The incidence of lung cancer in pulmonary nodules measuring ≥ 8 mm is not influenced by the presence of lung cancer risk factors.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
