Can a lung nodule be removed?
Unfortunately, cancers can also produce and appear as lung nodules. The risk that any nodule is cancerous depends most importantly on the size. Our board-certified thoracic surgeons are experts in video-assisted thoracic surgery (VATS), often done to biopsy nodules and determine whether they need to be removed.
About 40 percent of pulmonary nodules turn out to be cancerous. Half of all patients treated for a cancerous pulmonary nodule live at least five years past the diagnosis. But if the nodule is one centimeter across or smaller, survival after five years rises to 80 percent. That's why early detection is critical.
- They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. A larger lung nodule, such as one that's 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule.
- Causes of Lung (pulmonary) Nodules. Benign lung nodules can be caused by a variety of factors including the following: scarring in the lung caused by a prior infection (fungus, pneumonia, or tuberculosis and sarcoidosis which cause the formation of a unique type of scar called a granuloma.
- Focal nodular hyperplasia (FNH) is a tumor-like growth made up of several cell types (hepatocytes, bile duct cells, and connective tissue cells). Although FNH tumors are benign, it can be hard to tell them apart from true liver cancers, and doctors sometimes remove them when the diagnosis is unclear.
noninfectious diseases that cause noncancerous nodules, such as sarcoidosis and rheumatoid arthritis. neoplasms, which are abnormal growths that can be benign or cancerous. cancerous tumors, such as lung cancer, lymphoma, sarcoma. metastatic tumors that spread from other parts of the body.
- Needle biopsy. After a local anesthetic is given, the doctor uses a needle that is guided through the chest wall into a suspicious area with computed tomography (CT or CAT scan) or fluoroscopy (a type of X-ray “movie”) to obtain a tissue sample.
- A benign lung tumor is an abnormal growth of tissue that serves no purpose and is found not to be cancerous. Benign lung tumors may grow from many different structures in the lung. Determining whether a nodule is a benign tumor or an early stage of cancer is very important.
- Among the most common causes of noncancerous lung nodules are scars or marks from a prior fungal infection, such as histoplasmosis or coccidiodomycosis, a bacterial infection, a mycobacterial infection such as tuberculosis, or a benign tumor called a hamartoma. Lung nodules are common.
Causes of Multiple Lung Nodules. Multiple pulmonary nodules may be caused by malignant or benign diseases. Some of the more common causes include: Benign tumors can also develop in the lungs, the most common of which are tissue malformations called hamartomas.
- “Pleural-based nodule” just means a nodule that is right on or below the lining of the lung, called the pleura. It's not the same as a pleural effusion, which is a collection of fluid in the space between the outside of the lung and the inside of the chest wall.
- fibrocystic breasts, a condition in which breast tissue feels lumpy in texture and is sometimes accompanied by pain. fibroadenoma, meaning noncancerous rubbery lumps that move easily within the breast tissue and rarely become cancerous. hamartoma, which is a benign, tumorlike growth.
- There is no cure for sarcoidosis, but most people do very well with little or only modest treatment. In half of cases, sarcoidosis goes away on its own. In a few cases, however, sarcoidosis may last for years and may cause organ damage.
