Sybil is able to detect early signs of lung cancer. These CT scans, from the same patient, were taken two years apart. In the scan on the left, the area highlighted in red is what Sybil detected.
The results showed that more frequent screening resulted in higher resectability rate (more early-stage detection) but made no difference in mortality from lung cancer. Chest x-ray screenings were found to detect 6 times as many new cancers as sputum tests, proving the disutility of sputum tests in lung cancer screening. [ 17 ]
Lung cancer most commonly metastasizes to the brain, bones, liver, and adrenal glands. [14] Lung cancer can often appear as a solitary pulmonary nodule on a chest radiograph or CT scan. In lung cancer screening studies as many as 30% of those screened have a lung nodule, the majority of which turn out to be benign. [15]
Plus, what you can do to lower your risk—besides not smoking.
Non-small cell lung cancer (NSCLC) is the most prevalent form of lung cancer, comprising 81% of all diagnosed cases. Early detection significantly improves prognosis; however, diagnosing NSCLC and other lung cancers can be challenging since their symptoms are often mistaken for common illnesses or long-term smoking effects.
The impact of early cancer detection and the treatment outcomes vary, as there are instances where even with available treatment, early detection may not enhance the overall survival. If the cancer screening does not change the treatment outcome, the screening only prolongs the time the individual lived with the knowledge of their cancer diagnosis.
