How is lung cancer diagnosed?
-
Usually a mass is found in the lung. There are various ways this mass can be biopsied to determine if it's cancer. The most common is to have bronchoscopy, in which a lighted tube is inserted into the lung. Biopsies are attained as this tube approaches the lung mass. Another way to diagnose lung cancer is to have a computerized tomography (CT) guided biopsy in which an area on the skin over the mass is anesthetized and a needle is inserted into the chest to retrieve tissue from the mass. The tissue is then forwarded to a pathologist for review under a microscope.

Johns Hopkins Medicine answered:Lung cancer is usually diagnosed by X-rays and CT scans that provide images of the lung and show if a tumor is present. Other tests used to diagnose lung cancer are:
• Examination of cells – cells obtained from sputum are examined under a microscope to see if they contain cancer cells.
• Fiberoptic examination – under anesthesia, a thin, fiberoptic camera is inserted into the bronchial passages of the lungs to examine the organ for tumors or lesions.
• Biopsy – a small sample of cells is removed from the tumor and examined for cancer cells under a microscope to see if it contains cancer cells.Helpful? 1 person found this helpfulLung cancer is usually diagnosed by X-rays and CT scans that provide images of the lung and show if a tumor is present.

The only accurate way to diagnose lung cancer is a biopsy of the lung nodule or growth. Some patients can receive a needle biopsy—a needle is inserted directly into the nodule through the chest wall and cells are extracted from that nodule for examination under a microscope. Other patients, who have nodules that are located too deep in the lung or are too small to be biopsied, may require a surgical biopsy—the biopsy is performed as part of the surgery to remove the nodule. Other tumors can be biopsied through a bronchoscope that is introduced through the airwayThe only accurate way to diagnose lung cancer is a biopsy of the lung nodule or growth.

Dr. Patrick Maguire answered:It's extremely common for the diagnosis of lung cancer patients to have a chest x-ray that reveals a mass and prompts further evaluation with a computerized tomography (CT) of the chest. If the CT scan confirms a lung mass suspicious for cancer, then a CT-guided biopsy may be performed by a radiologist for diagnosis. Positron emission tomography/computerized tomography (PET/CT) scans may also be performed to further evaluate suspicious lung lesions that are seen on CT, prior to biopsy. Some masses are so suspicious that direct surgical resection is recommended.
Lung cancer diagnosis can also be made by bronchoscopy. If the tumor is visualized within the bronchial tree, then it may be biopsied. More recently, a procedure called endoscopic bronchial ultrasound (EBUS) has been shown to be fairly accurate with diagnosis by biopsying not only primary lung lesions but also enlarged lymph nodes in the mediastinum, the area in the center of the chest between the lungs. Approximately 75% of lung cancers are nonsmall cell (NSCLC). Most of the remaining 25% are small cell lung cancers. This differentiation is important since treatment of the two different types may be quite different.It's extremely common for the diagnosis of lung cancer patients to have a chest x-ray that reveals a mass and prompts further evaluation with a computerized tomography (CT) of the chest.

Symptoms or incidental findings on imaging lead to an investigation for lung cancer. Diagnosis requires a tissue sample usually obtained by a biopsy.Symptoms or incidental findings on imaging lead to an investigation for lung cancer.

Dr. Vijay Nuthakki of Aurora Health Care answered:Lung cancer is usually diagnosed through different tests. X-rays and CT scans are common tests that can provide images of your lungs to see if any abnormalities are present. If there are abnormalities that are suspicious for cancer then a confirmation is needed with evaluation of tissue. Tissue can be obtained by biopsy with CT guidance, bronchoscopy, or surgery. In other cases, if you have a cough with mucus or phlegm, your doctor may exam that to see if lung cancer cells are present. Lastly, your doctor may examine a tissue sample to check for lung cancer, which can be obtained in a variety of ways.
