The lungs, located at the center of the chest, primarily filter harmful substances invading the body. Prolonged exposure to toxins can compromise lung function. With rising lung cancer incidence rates, doctors emphasize the importance of regular lung screenings. Among various lung cancer detection methods, lung CT scans are common. High-resolution CT scans reveal minute abnormalities within the lungs.Compared to X-rays, CT scans provide more detailed imaging and accurately distinguish between abnormal and healthy tissue. While radiation exposure from CT scans may raise concerns about unnecessary testing, low-dose, regular screenings pose no harm. The following individuals should undergo periodic lung CT scans:
Who needs regular lung CT scans?
1. Smokers
Tobacco is now clearly recognized as a cause of lung cancer. The earlier one starts smoking, the longer the smoking history, and the greater the daily cigarette consumption, the higher the risk of developing lung cancer. Therefore, individuals with smoking habits and a certain smoking duration should promptly undergo lung CT scans to understand their condition.
2. Long-term exposure to secondhand smoke
Prolonged exposure to secondhand smoke also increases lung cancer risk. Harmful substances from tobacco are inhaled by those around the smoker, damaging lung tissue upon entry. Regular screening is essential for individuals chronically exposed to secondhand smoke.
3. Underlying medical conditions
Individuals with conditions such as dermatomyositis, Sjögren's syndrome, or chronic obstructive pulmonary disease (COPD) face a higher risk of lung cancer than the general population. Regular screenings are particularly important when lung diseases progress unchecked, as they can help reduce the likelihood of these conditions developing into lung cancer.
4. Prolonged Exposure to Carcinogens
Research indicates radon is one of the most dangerous carcinogens, primarily originating from building materials and interior finishes. Consequently, indoor pollution is now recognized as the second leading cause of lung cancer. This substance can be found in schools, offices, and homes. Workers such as construction laborers, chefs, and asbestos factory employees are most susceptible to exposure. Those with prolonged contact should remain vigilant and undergo regular screenings.
Important Reminder
As we age, lung function naturally declines. Regular check-ups can lower lung cancer incidence and provide insight into lung health. Seek medical attention promptly if you experience chest tightness, persistent coughing, or coughing up blood. Follow your doctor's guidance for examinations. Prepare for tests by removing metal objects beforehand to ensure accurate results and prevent misinterpretation by physicians.
