A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules.
Studies of whole body screening computed tomography find abnormalities in the lungs of 14% of patients. [17] Clinical practice guidelines by the American College of Chest Physicians advise on the evaluation of the solitary pulmonary nodule. [18]
The criteria for diagnosing pulmonary adenocarcinoma have changed considerably over time. [10] [11] The 2011 IASLC/ATS recommendations, adopted in the 2015 WHO guidelines, use the following criteria for adenocarcinoma in situ: [12] tumor ≤3 cm; solitary tumor; pure "lepidic" growth* [13] No stromal, vascular, or pleural invasion
Thoracic radiotherapy generally begins with the first or second cycle when chemotherapy is used according to most guidelines. [19] The time between the start and the end of chemoradiotherapy is a predicator of survival in limited stage small cell lung cancer, prolongation leads to a decrease in overall survival of 1.9% per week.

Pulmonary function: increased residual volume, increased total lung capacity, fixed obstruction, low diffusing capacity of the lung for carbon monoxide that corrects with alveolar volume; High-resolution CT scan: diffuse pulmonary nodules 4–10 mm, greater than 20 nodules, mosaic attenuation or air trapping in greater than 50% of the lung

Lung cancer most commonly metastasizes to the brain, bones, liver, and adrenal glands. [14] Lung cancer can often appear as a solitary pulmonary nodule on a chest radiograph or CT scan. In lung cancer screening studies as many as 30% of those screened have a lung nodule, the majority of which turn out to be benign. [15]
For lung nodules, air bronchograms used to be associated with infectious causes of consolidation and, therefore to be benign. However, in the setting of a lung nodule, an air bronchogram is actually more frequent in malignant than in benign nodules. [1] [4] studied the tumour-bronchus relationship and described five types: [1]
