What is Lung Cancer Screening?

Lung cancer screening can help find disease early, before symptoms occur.

What happens after the first screening LDCT?

  • Follow-up or yearly screening LDCT
  • Your doctor will compare your second screening test to the first screening test and decide when the next follow-up test will happen.
  • Follow-up screening is done to check on your lungs at certain time points like months or years.

When should I start screening?

Ideally start start before you have symptoms Symptoms can include:
cough that lasts, blood in mucus, shortness of breath, wheezing, pain in chest area, tiredness that lasts, pneumonia, hoarse voice, pain when swallowing, and weight loss.
Find out your level of risk Screening for lung cancer is an option for two high-risk groups:
• People 55-74 years old, who have smoked for 30 or more pack years, who quit less than 15 years ago.
• People 50 years old and over, who have smoked for 20 or more pack years, and have at least one more risk factor other than second-hand smoke.


Pack years – It is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years the person has smoked. For example, 1 pack-year is equal to smoking 20 cigarettes (1 pack) per day for 1year, or 40 cigarettes per day for half a year, and so on.

What is a LDCT (low-dose computed tomography)?

LDCT LDCT takes many pictures of the inside of your body from different angles using CT scan.
The amount of radiation used is much lower than standard doses of a CT (computed tomography) scan.
First LDCT If you are high risk for lung cancer you will have a LDCT test. Your doctor will check for anything abnormal like a lung nodule.
Lung nodules Screening with LDCT is used to find nodules in the lungs. Nodules are small, round areas of abnormal tissue.
