Lung CT-Scan

1. What is Low-Dose Lung Computed Tomography (Low-Dose CT)?

Low-Dose CT is an advanced imaging method that enables early detection of lung cancer in high-risk individuals, such as long-term smokers or those with a family history of lung cancer. With this method, the X-ray dose is reduced to a fraction of that used in standard CT scans, minimizing radiation exposure while still delivering clear and detailed images.

This technique is crucial for lung cancer screening, as early-stage lung cancer often presents no obvious symptoms. Detecting cancer early increases survival rates and allows for more effective treatment options. Annual low-dose CT scans can identify lung nodules when they are still very small and asymptomatic, significantly aiding in treatment and disease management.

The procedure is quick, taking only 5–10 minutes, and requires no special preparation, making it convenient, stress-free, and accessible for patients.

2. The Gold Standard for Lung Cancer Screening

🩺 Low-Dose CT is recognized as the gold standard for screening lung nodules and lung cancer.
🩺 It detects abnormal lung cells at their earliest stages, even when cancer signs are still microscopic. The radiation dose is minimal, posing no health risks, and scans can be performed at closer intervals than standard CT, enabling timely monitoring and treatment of tumor progression.

3. Who Should Undergo Low-Dose CT?

• Individuals with underlying health conditions or ongoing health concerns requiring monitoring.
• Those aged 50 and above, especially long-term smokers or individuals with a family history of lung cancer.
• Low-Dose CT is a safe, effective, and non-invasive option for lung cancer screening.

4. High-Risk Factors for Lung Cancer

• Smoking: The leading risk factor, responsible for 85–90% of lung cancer cases, including direct and secondhand smoke exposure.
• Genetics and Family History: A family history of lung cancer increases risk, with genetic predispositions playing a significant role.
• History of Lung Disease: Chronic conditions like pneumonia, tuberculosis, or pulmonary fibrosis heighten lung cancer risk.
• Unhealthy Lifestyle: Poor diet lacking fiber and vegetables, along with sedentary habits, weakens immunity and raises disease susceptibility.
• Other Factors: Air pollution, radon exposure, asbestos, and contact with harmful chemicals.
   

Advantages of Low-Dose CT

• Reduced X-ray exposure minimizes health risks.
• Enables early and precise detection of lung abnormalities.
• Facilitates timely monitoring and treatment, improving health outcomes.
