Yes. Lung cancer will show up in the computed tomography (CT) scan. CT scan combines various X-ray images taken at different angles and uses computer technology to form thin images of bones, tissues and blood vessels to give a detailed picture of the body.
Screening is not usually performed for lung cancer except in patients with risk factors. Low-dose computed tomography scan is the only recommended screening tool for lung cancer. The CT scan machine rotates the X-ray around the patient’s body through a circular machine called the gantry. Each time machine rotates, the information is stored in the computer. The patient is also moved up or down to take images of the whole body.
A (2021) study has found that ‘screening high-risk persons with low-dose computed tomography scan can reduce lung cancer mortality but also causes false-positive results leading to unnecessary tests and invasive procedures, overdiagnosis, incidental findings, increases in distress, and, rarely, radiation-induced cancers’.
