So you should think twice before you get the test. If 1, high-risk smokers get the test, about three will find lung cancer early enough to receive treatment and not die from lung cancer. Eighteen others will also find lung cancer, and will die even though they had the screening test.
CT scans have no benefits for people with low risk. Research has not shown that the test helps save lives in low-risk groups. CT scans cause many false alarms, even in high-risk people.
If high-risk smokers get the test, about 40 will show something that can cause concern. But only two or three actually have lung cancer. The false alarms often lead to follow-up tests.

However, needle biopsies remove only a small amount of tissue. This small amount of tissue may not provide enough information to diagnose cancer.
Your doctor will use a syringe that has a very thin, hollow needle to remove cells and tiny fragments of tissue from suspicious areas. An FNA is often performed to look for cancer cells in the lymph nodes between the lungs. Your doctor may use a larger needle to remove a larger sample of tissue from your airways. The large sample size is an advantage of having a core biopsy.
This type of biopsy may be done if your care team suspects a tumor is in the outer part of your lungs. During a transthoracic needle biopsy, a needle is inserted through the skin of your chest wall. You will be given local anesthesia to numb the area. The doctor uses a type of X-ray known as fluoroscopy or a CT scan to help guide the needle. A transthoracic needle biopsy may allow air to leak out of your lung and into the space between it and your chest wall.
Called a pneumothorax, it may cause your lung to collapse. If the leak is tiny, it should get better on its own without treatment. If the leak is large, your doctors will insert a chest tube into the space to suck out the air. It could take a day or two for all of the air to be removed, but it should heal on its own afterward.
Your doctor may use a bronchoscopy to look for tumors or blockages in the larger airways of your lungs. A bronchoscopy involves putting a bronchoscope, a thin flexible tube with a light and a video camera, down your throat and into your airways to have a look around. This technology allows our physicians to identify cancerous cells in the bronchial tubes that may not be visible under white light examination. The doctor can then remove a small sample of abnormal tissue for further analysis.
A navigational bronchoscopy combines advanced imaging techniques with electromagnetic navigation to help find and treat cancer in the lungs. This procedure allows doctors to reach tumors by advancing the scope into smaller bronchi or bronchi that are blocked by a tumor.
For patients who are candidates for lung cancer screening, or for those for whom an area of concern cannot be reached via traditional, navigational bronchoscopy, robotic bronchoscopy may be an option. Robotic bronchoscopy may help certain patients avoid a transthoracic needle aspiration, which may increase the risk of complications.
Robotic bronchoscopy is also designed to increase the chance of an accurate diagnosis. An endobronchial ultrasound is performed by inserting a flexible scope through the mouth into the larger airways and using high-frequency sound waves to image the tissue.
EBUS is a less invasive bronchoscopic procedure used to evaluate and sample cancerous cells in the chest. In most cases, EBUS is performed as an alternative to a mediastinoscopy , a surgical procedure used to collect samples in the chest while the patient is under general anesthesia. With this ultrasound, doctors insert an endoscopic ultrasound device into your esophagus to see whether nearby lymph nodes contain lung cancer cells.
Both of these tests are used to look more closely at the lymph nodes along your windpipe and bronchial tubes. Which procedure your doctor recommends depends on where the suspected spread is and how big a sample is needed.
With a mediastinoscopy , a lighted tube is placed behind your breastbone to help look around and take samples to be analyzed in a lab. A mediastinotomy requires an incision roughly 2 inches long be made between the second and third ribs on your left side.
This procedure allows your doctor to also look around and collect samples for analysis. Your doctor may order a thoracoscopy to determine whether your cancer has invaded the space between your lungs and chest wall or the lining of these spaces. Your doctor will use a thoracoscope—a thin, flexible tube that has a light and a tiny video camera on the end of it—to see inside your chest.
The tube is inserted through a small incision that is made between your ribs and the bottom of your shoulder blade. This type of procedure may also be performed as a part of video-assisted thoracic surgery VATS. Thoracoscopy also may be used in some cases as a treatment for early-stage lung cancer. The part of your lung where the cancer is located may be removed using this procedure. Your doctor also may order the following tests to aid in your diagnosis and determine your individual treatment plan:.
Currently, no blood test can detect lung cancer. Blood tests that your doctor may order include:.
