A need exists for non-invasive testing to aid in clinical decision-making for CT scan detected lung nodules of indeterminate etiology. The investigators hypothesize that biomarkers detectable in blood, sputum or urine may be useful for guiding clinical decisions in the setting of CT detected lung nodules to determine which nodules are malignant and which are benign. The investigators also hypothesize that these biomarkers will decrease in concentration to the normal range after successful surgical treatment of malignant lung nodules.
The Biomarkers for Diagnosis of Lung Nodules Study is a prospective study of a cohort of 600 individuals with lung nodules of indeterminate etiology that are identified by CT scans. Either biopsy or repeat CT scans must be clinically indicated to determine the etiology of the nodule. Patients will be asked to allow investigators access to CT scan images and spirometry data, and provide blood, sputum, urine, and exhaled breath samples over the course of the study. Patients will also be asked to allow investigators to access pathology records if a biopsy or surgical excision of the nodule is clinically indicated.

The diagnosis of lung abscess can be difficult to make and often requires imaging beyond plain chest x-ray. The decision to further image with computed tomography should be weighed against the risks o...
Lung abscess was previously treated surgically, but is now mainly treated with antibiotics and ideally with direct drainage, although postural drainage canalso be used.

Solitary or multiple collections of PUS within the lung parenchyma as a result of infection by bacteria, protozoa, or other agents.
Accumulation of purulent EXUDATES beneath the DIAPHRAGM, also known as upper abdominal abscess. It is usually associated with PERITONITIS or postoperative infections.
Abscess of the PSOAS MUSCLES resulting usually from disease of the lumbar vertebrae, with the pus descending into the muscle sheath. The infection is most commonly tuberculous or staphylococcal.
A rehabilitation therapy for removal of copious mucus secretion from the lung of patients with diseases such as CHRONIC BRONCHITIS; BRONCHIECTASIS; PULMONARY ABSCESS; or CYSTIC FIBROSIS. The patient's head is placed in a downward incline (so the TRACHEA is inferior to the affected area) for 15- to 20-minute sessions.
An abscess located in the abdominal cavity, i.e., the cavity between the diaphragm above and the pelvis below. (From Dorland, 27th ed)
