Low-Dose CT Lung Cancer Screening
Early detection is a proven, successful strategy for fighting many forms of cancer. Seattle Cancer Care Alliance offers screening with low-dose computed tomography (CT) for people at high risk for lung cancer, the only recommended screening test for the disease.
Lung cancer is the leading cause of cancer-related death in the United States. Three out of four people with lung cancer have incurable, locally advanced, or metastatic disease at the time of diagnosis. Their five-year survival rate is less than 5 percent when diagnosed with stage IV lung cancer.
Detecting lung cancer at its earliest stage, and having it surgically removed, means a person can expect a five-year survival rate closer to 53 percent. Yet only 15 percent of cases are diagnosed at such an early stage.
People at high risk for lung cancer who benefit from annual screening with low-dose CT according to new guidelines published by the U.S. Preventive Services Task Force are between 55* and 80 years old and smoked at least an estimated
- 1 pack a day for 30 years OR
- 2 packs a day for 15 years, unless you quit smoking more than 15 years ago.
*If you are younger than 55, high false-positive rates in lung cancer screening may have more harms than benefits, leading to more radiation from more imaging, anxiety, and in some cases, lung surgery to determine a diagnosis.
In addition to the above characteristics, you are considered at high risk for lung cancer if you have one additional risk factor:
- Documented high radon exposure
- Occupational exposure to silica, cadmium, asbestos, arsenic, beryllium, chromium, nickel or diesel fumes
- Are a survivor of lung cancer, lymphoma, or head and neck cancer
- Have a history of chronic obstructive pulmonary disease or pulmonary fibrosis
- Have a family history of lung cancer
It is unknown if this second group of high-risk patients will benefit from CT screening since there are no data to address this question.
Secondhand smoke exposure is NOT an independent risk factor for lung cancer CT screening.
Cost for CT Scan
Your insurance company will be billed for the low-dose CT screening, but there is a high likelihood that the screening exam will not be a covered benefit. The out-of-pocket cost for the CT screen is $300. Most follow-up care required after the exam will be covered by your insurance or Medicare/Medicaid. Check with your insurance carrier to make sure.
