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. One or more lung nodules can be ...
T3 centr: Primary tumor is <2 cm to the carina or there is atelectasis of the entire lung; T3 satell: Primary tumor is associated with separate tumor nodule(s) in same pulmonary lobe; T4 inv: Tumor invading the heart, great vessels, trachea, recurrent laryngeal nerve, esophagus, or spine;
Tar is occasionally referred to as an acronym for total aerosol residue, [3] a backronym coined in the mid-1960s. [4] Tar, when in the lungs, coats the cilia causing them to stop working and eventually die, causing conditions such as lung cancer as the toxic particles in tobacco smoke are no longer trapped by the cilia but enter the alveoli ...
A 2022 report from the American Lung Association indicated that only 5.8% of Americans had been screened for lung cancer and that in some states, rates were as low as 1%.
For that reason, lesions greater than 5 centimetres (2.0 in) should be excluded, and lesions 3 to 5 cm (1.2 to 2.0 in) should be considered with caution, given high risk of recurrence. Additionally, for safety reasons, lesions less than 1 cm ( 3 ⁄ 8 in) from the trachea, main bronchi, esophagus and central vessels should be excluded from RFA ...
In addition, at the time of diagnosis, 57% of lung cancers are discovered in advanced stages (III and IV), meaning they are more widespread or aggressive cancers. [2] Because there is a substantially higher probability of long-term survival following treatment of localized (60%) versus advanced stage (6%) lung cancer, lung cancer screening aims ...

By definition, they are greater than 4 mm in largest dimension; smaller lesions are referred to as pulmonary carcinoid tumourlets. [citation needed] The differential diagnosis of typical pulmonary carcinoid tumour includes: atypical pulmonary carcinoid tumour, pulmonary carcinoid tumourlet and lung adenocarcinoma.
