Check Early: Could You Have Lung Cancer?

 

Lung cancer is one of the most common cancers in both men and women, with a mortality rate of over 25%.

๐ Stage 1: 5-year survival rate ≈ 68-92%

๐ Stage 4: 5-year survival rate ≈ 0-10%

 

What is Low-Dose CT Lung Cancer Screening?

 

Low-Dose CT (LDCT) is a chest scan using a lower radiation dose to detect lung abnormalities at an early stage.

 

Advantages of Low-Dose CT Scan

 

๐ Produces 3D images (more detailed than chest X-ray)

๐ Detects lung cancer at an early stage

๐ Uses 5-6 times less radiation than standard CT

๐ No contrast injection required

๐ Fast procedure (5-10 minutes)

๐ No need to fast

 

Who Should Get Screened?

 

According to U.S. Preventive Services Task Force, screening is recommended for high-risk individuals:

๐ Age 50-80 years

๐ Smoking history ≥ 20 pack-years

๐ Currently smoking OR quit within the past 15 years

 

Why Choose Low-Dose CT Over Chest X-ray?

 

Studies show that LDCT:

๐ Detects early-stage lung cancer more effectively

๐ Significantly reduces mortality rates compared to chest X-ray

 

How Often Should You Get Screened?

 

If results are normal - once per year

If abnormalities are found 

๐ Follow-up within 1-6 months

๐ Additional imaging or biopsy may be required

 

Do Non-Smokers Need Screening?

 

Yes, if you are at high risk, such as:

๐ Family history of lung cancer

๐ Chronic lung disease

๐ Exposure to carcinogens (incense smoke, secondhand smoke)

Summary

 

Lung cancer is deadly-but early detection saves lives.
