What is a Lung Nodule? A lung nodule is a mass of tissue located in the lungs. Though about 40% of these growths are benign, they can be cancerous, especially in older people and smokers. Many people with this condition don't have any symptoms, though some do have wheezing, shortness of breath, or a persistent cough.edical professionals can examine chest X-rays for indications of lung nodules. Smokers are at a serious risk of developing lung nodules. A lung nodule is a mass of tissue located in the lungs. Cancerous lung nodules may be removed through a surgical procedure.

Spot on the lungs Noncancerous pulmonary nodules can develop from conditions that cause inflammation or scar tissue on the lungs. Possible causes include: lung infections, such as mycobacterium tuberculosis; granuloma, which are small clumps of cells that grow because of inflammation; noninfectious diseases that cause noncancerous nodules, such as sarcoidosis and rheumatoid arthritis; neoplasms, which are abnormal growths that can be benign or cancerous

Solitary Pulmonary Nodule A solitary pulmonary nodule is defined as a discrete lesion < 3 cm in diameter that is completely surrounded by lung parenchyma (ie, does not touch the hilum, mediastinum, or pleura) and is without associated atelectasis or pleural effusion. (Evaluation of a mediastinal mass is discussed elsewhere.)

Benign Lung Tumors and Nodules 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.

What Does Having a Nodule on the Lung Mean? Definition of Lung Nodules. A lung nodule is defined as a “spot” on the lung that is three centimeters (about 1.5 inches) in diameter or less. If an abnormality is seen on an x-ray of the lungs that is larger than three centimeters, it is considered a “lung mass” instead of a nodule and is more likely to be cancerous. Lung nodules usually need to be at least one centimeter in size before they can be seen on a chest x-ray.

Lung Nodule Jefferson's Lung Nodule Clinic, one of the first in the Delaware Valley, is staffed and organized by a nurse coordinator and pulmonary medicine specialists with expertise to further evaluate lung nodules. Typically a lung nodule isn't a cause for concern as 80 percent are found to be noncancerous (benign).

Solitary Pulmonary Nodule - Topic Overview Pulmonary (lung) nodules are growths or spots in the lungs. You may have just one nodule (called a solitary pulmonary nodule) or more than one (called multiple nodules). Lung nodules may be caused by: A lung cancer. A cancer that has spread (metastasized) to the lung from another part of the body.

- The challenge is figuring out which nodules are or will become cancer. All lung cancer starts with a nodule but 95% of lung nodules are not cancer. Nodules that are not cancer may be the result of a bacterial or fungal infection in the past that causes inflammation and scarring in the lungs.f it is lung cancer, the biopsy should show the type of lung cancer, either non-small cell or small cell.There are a number of ways that tissue or fluid can be removed by biopsy. The type of procedure is determined by the size of the nodule, where it is located in the lung and your overall health.

Lung Nodules A lung nodule is defined as a “spot” on the lung that is 3 cm (about 1 ½ inches) in diameter or less. If an abnormality is seen on an x-ray of the lungs that is larger than 3 cm, it is considered a “lung mass” instead of a nodule, and is more likely to be cancerous.

Lung Nodules The most common causes include granulomas (clumps of inflamed tissue) and hamartomas (benign lung tumors). The most common cause of malignant lung nodules include lung cancer, or cancer from other regions of the body that has spread to the lungs (metastatic cancer).

Solitary Pulmonary Nodule A solitary pulmonary nodule (SPN) is a single abnormality in the lung that is smaller than 3 cm in diameter. Generally, a pulmonary nodule must grow to at least 1 cm in diameter before it can be seen on a chest X-ray. An SPN is surrounded by normal lung tissue and is not associated with any other abnormality in the lung or nearby lymph nodes (small, bean-shaped structures found throughout the body).

Does a lung nodule mean cancer? A: The term nodule is usually used to describe a small rounded growth or lump. This can appear anywhere on or in the body. Or it may be found on an X-ray or other type of scan. Nodules can be a sign of cancer, but more often they are benign (noncancerous) growths. Pulmonary nodules are small rounded growths in the lung. They're usually found on chest X-rays or CT scans. Causes of pulmonary nodules include:

The Radiologic Appearance of Lung Cancer A solitary pulmonary nodule (SPN) is the most common radiographic presentation of lung cancer. The imaging characteristics of solitary pulmonary nodules are described and illustrated.The appearance and implications of extension of lung cancer to the pleura are explored.he radiologic work-up of the solitary pulmonary nodule is pursued to facilitate the resection of potentially curable lung cancers and to minimize the resection of benign nodules. Neoplasm can often be strongly suspected or excluded based on the radiologic characteristics of the solitary pulmonary nodule.
