At CTCA, we recommend you undergo yearly lung cancer screenings if you're at high risk of lung cancer e. Lung cancer screenings are like mammograms or colonoscopies: a yearly test that checks to see whether high-risk individuals have developed suspicious signs of cancer, or if cancer does develop, helps catch it as early as possible.
While mammograms and colonoscopies have garnered significant awareness over the years, the percentage of people who undergo yearly lung cancer screenings is very low.
In fact, among people eligible for yearly lung cancer screenings in the United States, only about 3 percent get screened. The United States Preventive Services Task Force advises that you're at high risk of lung cancer if both of these apply to you:. These doctors may be better equipped to offer the proper guidance and order further testing when appropriate to determine whether you have lung cancer.
You might also want to consider getting a second opinion. Getting a second opinion from a cancer center with a multidisciplinary approach to cancer diagnosis and care may help alleviate the stress and anxiety that comes with finding out you have a lung nodule. Many patients come to CTCA for a second opinion because of our personalized approach to cancer care and comprehensive treatment options. Patients with lung nodules, specifically, come to us for a second opinion because of our unique rapid lung-nodule diagnosis program.
We've seen many patients left stressed and anxious for weeks or months after finding out they have nodules in their lungs. We also know how crucial time is when it comes to diagnosing and treating lung cancer.
Before you even get to your first scheduled appointment, our team of cancer experts has already researched and reviewed your CT scans. Our tumor board consists of interdisciplinary experts, including an interventional radiologist , an interventional pulmonologist , a thoracic surgeon , a medical oncologist and a radiation oncologist—all reviewing your CT scans and medical records together. Working together, we can better identify whether your lung nodules are suspicious for cancer.
If they are, we schedule the appropriate tests as quickly as possible. If you don't have lung cancer, we all celebrate and you go on your way. The nodule will show as a spot or shadow on the X-ray. If an X-ray shows signs of a nodule, the doctor may request a follow-up CT scan.
This type of imaging test can provide more detail than an X-ray. After finding a lung nodule, the doctor will assess its size, shape, and appearance. Certain features may suggest that the nodule is more likely to be cancerous. For example, larger nodules are more likely to be cancer.
The location, shape, and size of the nodule may increase its risk of malignancy. When the features of the nodule suggest malignancy, the doctor may recommend a biopsy.
This procedure involves removing a small amount of tissue from the nodule, either using a needle or during a bronchoscopy. A bronchoscopy involves inserting a thin tube down the windpipe and into the lung through the mouth or nose. The tube has a small camera, which allows the doctor to view the airways.
They will then use special tools to obtain a tissue sample from the nodule. Another option is a needle biopsy, which involves inserting a needle into the lung through the chest wall. A doctor will usually use a CT scan to guide the insertion. The procedure healthcare providers use to access a tissue sample depends on the size and location of the nodule. After obtaining the sample, the doctor sends the tissue to a laboratory.
A pathologist will examine the tissue under a microscope to look for cancerous cells. A doctor will not always need to perform a biopsy when a person shows lung nodules.
If an individual is low risk, and the features of the nodule suggest a low likelihood of cancer, a biopsy may cause more harm than good. Performing a biopsy on a small lung nodule can be difficult, and complications, such as bleeding or a collapsed lung, might occur.

Recap To diagnose a lung nodule, your healthcare provider will ask you about your history and risk factors. Low Risk of Lung Cancer Under age 35 Nodule is small less than 3 cm in diameter Patient is a nonsmoker and has never smoked No exposure to toxins in the workplace No history of lung cancer among family members No other signs or symptoms of lung cancer Nodules are smooth and round in shape Nodules are only partly solid Nodules do not get bigger over time Nodules are calcified contain calcium deposits Interior of nodule is "cavitary"—darker on X-rays Only one or a few nodules are present.
High Risk of Lung Cancer Over age 50 Nodule is larger than 3 cm in diameter Patient smokes or is a former smoker Exposure to occupational toxins such as asbestos or radon First- or second-degree relative with lung cancer Presence of lung cancer symptoms such as persistent cough or shortness of breath Nodules are "spiculated"—have irregular or lobe-shaped borders Nodules are solid Nodules grow rapidly on average doubling in size in four months Nodules show no signs of calcification Nodules are not cavitary Presence of multiple nodules may indicate cancer metastases to the lungs.
Recap If you're between the ages of 50 and 80, you smoke, you quit within the last 15 years, or you have a 20 pack-year smoking history, you should be screened for lung cancer every year.
