Lung Cancer Screening: A Lifesaving Measure for Millions More Adults
Lung cancer is the leading cause of cancer death in the United States, accounting for nearly one in four cancer deaths. But early detection through screening can significantly improve survival rates.
What is LDCT?
LDCT is a type of X-ray that uses a lower dose of radiation than traditional CT scans. LDCT is used to create detailed images of the lungs, which can help doctors detect cancer early.
Who should get screened for lung cancer?
The USPSTF recommends lung cancer screening for adults aged 50 to 80 who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. A pack-year is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years smoked. For example, a person who smoked one pack of cigarettes per day for 20 years would have a 20 pack-year smoking history.
People with other risk factors for lung cancer, such as exposure to second-hand smoke or a family history of lung cancer, may also want to talk to their doctor about screening.
Benefits of lung cancer screening
Early detection of lung cancer through screening can lead to better outcomes. When lung cancer is caught early, it is more likely to be cured. Early detection can also help people avoid the need for more invasive and aggressive treatments.
Risks of lung cancer screening
LDCT scans are very safe, but there are a few potential risks, such as:
* False positives: LDCT scans can sometimes detect abnormalities that are not cancer. This can lead to unnecessary follow-up tests and anxiety.
* False negatives: LDCT scans can sometimes miss small cancers.
* Radiation exposure: LDCT scans expose people to a small amount of radiation. However, the risk of radiation-induced cancer is very low.
Talking to your doctor about lung cancer screening
If you are eligible for lung cancer screening, talk to your doctor about the benefits and risks. Your doctor can help you decide if screening is right for you.
